The Summer I Turned Pretty season three is officially over, and while I'm bereft, I've loved every single episode and the final one was *chef's kiss*. The show is based on the books by Jenny Han and she is the life and soul of the show, as she also serves as the show's creator and everything is considered - including the fashion.
I've loved seeing Belly Conklin's outfits in the show and finding out where they're from, and the best lookalikes to get the look. Season three saw Belly dealing with more drama around brothers Jeremiah and Conrad. Belly (played by Lola Tung) found herself at a crossroad, having to decide which brother has her heart. Throughout the third and final series we see her go from Cousins to Paris, and her style evolves throughout the series.

Who's the stylist for The Summer I Turned Pretty?
The costume designer for the show is Jessica Flaherty. She worked closely with author Jenny Han to create the show's relatable and cool fashion style, particularly for the character Belly.
She told People: "Because we shoot in summer and then we don't air until the next summer, a lot of times we've cycled out of those looks. But what I love about what Jenny and I have created with the show is that I feel like there's an essence about it that it feels timeless. It feels like you can still recreate these looks in your own way now and it keeps evolving."
She continued: "There's something really classic and dreamy and timeless and a little bit vintage, but also cool and hip. That all comes from my collaboration with Jenny, and just kind of following her vision. That's what I really do appreciate about the show, that it's not as much trend specific as it is a feeling and a vibe that you can have anytime."
Belly's fashion in series 3

Belly's Infinity Necklace
How genius is the collaboration between Amazon Prime and CatBird NYC. The two power houses have joined forces on a collection for The Summer I Turned Pretty and the infinity necklace is going to be an instant hit with fans.
Talking about the infinity necklace, Jessica said: "In the first season where we were sourcing everything and trying to figure out what it would look like, it was between showing different references and different things that we found until we landed on it. I didn't actually make the jewelry pieces, but it's sort of figuring out the width and how delicate, and how long, and where it's going to hit. It seems silly because it's just a necklace, but it's everything. Because that's how we see it, where does it hit exactly, at what point on her neck? We finally landed on this one, which I thought was just beautiful, and delicate, and perfection."

Belly's Paris Sightseeing Look With Conrad
It's Belly in Paris! Excuse the terrible images, these are snippets taken from the Instagram trailer for the final episodes of Belly being in Paris. Here she's wearing a Max Mara knitted vest and shorts combo - tres chic. Her shoes are the royal loved wedges of choice - the Castaner 'Carina' style in ivory.
If you're looking to copy the look for less, I love these Tuckernuck shorts for $148. Style with this near-identical vest tank top from Buffalo - it's so similar to Belly's!

Belly's Birthday Dress In Paris
Tres chic in Paris! Belly wore the La Robe Maille Croissant Minidress by Jacquemus for her birthday bash. The sexy mini is no longer in stock but I have found this stunning dress from Revolve that gives off a similar vibe.
Belly has teamed her mini with a pair of Parisian-looking Carel 'Kina' mary jane shoes. These are $550 but I have found a more affordable option from Zappos for $168.

Belly's Yellow Dress
Belly and THAT yellow dress. Fans of the show were convinced we'd see Belly in the yellow dress she wears in the artwork for the show, and lo and behold it made its appearance in the final scene of the show. This particular yellow dress is from Simkhai, priced at $495. It's pretty much all sold out, but I have found a near-identical one that's a much more affordable price from More To Come via Revolve.
Belly's wearing her dress with her Castaner ivory espadrille wedges.

Belly's Red Peter Pan Christmas Pjs
In the end credits we see Belly and Conrad's photo album from their Christmas in Paris. The pair could be seen opening gifts in their PJs and Belly's red pair the Paz pajamas by Doen which have sadly sold out but this pair from YesStyle have a similar vintage vibe. If you're after a pair of festive whimsical pajamas, I've found these from Petite Plume.

Belly's Sparkly Halter Top In Paris
Girls just wanna have fun - always. Belly and Taylor can be seen dancing on NYE when Taylor visits Belly in Paris, and I'm obsessed with the sparkly looks. These have been tricky to track down, but I have found some looks inspired by Belly's top. This Revolve sparkly silver crop top is pretty perfect, as is this halter from ASOS. Need. Immediately.
As for Taylor, her dress (which Taylor Swift has also worn) is likely Rabanne. But I adore this Dress The Population dupe.

Belly's Outfit The Morning After The Night Before
Tensions are high at the start of episode 8 when Belly sees Conrad again after their interaction on the beach at the end of the previous episode. In this scene Belly is wearing a Reformation co-ord called the 'Valetta' two-piece.

Belly's Wedding Rehearsal Dress
For the wedding rehearsal dinner, Belly is wearing the Staud white poplin dress, $375 and she's teaming it with a pair of shoes by Schutz.
If you want a similar look, how about this lookalike dress from Dynamite Clothing for just $139.95?

The Red Bikini
Belly swims in the pool on the night before her wedding day, and for this scene she's wearing a red triangle bikini with drawstring bottoms. I currently don't know where her exact bikini is from but Revolve has a solid lookalike, as does Target if you're looking for something a bit more reasonably priced.

Belly's Pink Stripe Smock Pajamas
Belly's adorable striped pink PJs are from The Great, but are sadly sold out. Don't worry though as I've found this lookalike pair from Reese Witherspoon's brand Draper James.

Belly's Pink & White Striped Robe
Belly's pink and white stripe robe is from Victoria's Secret, but her exact style has since sold out. Luckily it's back with a slightly different logo. This has been trending on the website ever since the show aired.
If you love Belly's Brouk and Co cosmetics case, you'll be pleased to know it's still available to buy at Gap.

Belly's Victoria Beckham Wedding Dress
Belly's wedding dress is the floor length ivory Victoria Beckham dress, priced at $1,250.
If you're looking for similar but for a fraction of the cost, how about this AWBridal dress? Or a gorgeous dress I've spotted on Revolve for $250.

Belly's Blue Rucksack
When Belly is leaving Cousins she is carrying her Coachtopia rucksack in blue. Sadly her color way has sold out but black is still available. You can shop on Amazon though! Belly's green suitcase you see at the airport is from Away and it's currently on sale.

The Shell Key Charm
When Belly leaves her key for the beach house, she drops down the Coach shell bag charm on the kitchen counter. This is part of the Coach x Summer I Turned Pretty collection.

The White Bachelorette Mini Dress
Episode 7, oh my goodness. Apart from the drama, I loved all the outfits for Belly's bachelorette party. The bride-to-be wore the American Eagle x The Summer I Turned Pretty mini dress which is so affordable. I've found the perfect lookalike for this dress from Cotton Candy LA and it's only $78.
If you're in the UK and after something with a similar look, I love this Urban Outfitters white mini dress for £49.
If you want more white dress options, check out this edit of the best white dresses.
Not photographed, but the purse she decided to wear was her go-to Coach 'Tabby' shoulder bag, $450 / £375.

The Blue Bow Bikini
For the pool party during the bachelorette, Belly can be seen wearing a bikini with blue bows all over - the perfect bridal bikini with a token 'something blue'.
It turns out her bikini is still available to shop from Solid & Striped.

The Green Polka Dot Dress
What do you wear to go apartment searching with your future husband? If you're Belly, you're wearing Reformation. Sadly this dress is a past season, but don't worry, I've found the ultimate lookalike from Walmart for just $8.99.

Consider yourself warned, this two-piece from Reformation is selling at the speed of light. Talk about the Belly Effect! If your size is out of stock, you could try a different style - the Andres Knit Two Piece is so ideal for fall.
Belly's cream slip-on shoes may well b sole out but the newer version has just dropped online.
In this scene she has accessorized with the Catbird NYC Daisy charm necklace, the Coach Tabby chain bag, $295 / £325.

Belly's Bachelorette Blue Mini Dress
Another day, another Reformation dress. Belly's girly bachelorette party look included the Zenni dress in blue by Reformation. Right now you can shop the exact dress but in an ivory shade for $298. If you're reading this in the UK, it'll be £298.
Of course show Belly's Coach 'Tabby' shoulder bag, $450 / £375 made another appearance.

Belly's Light Blue Top & Levi's Shorts
Doen was the designer of choice for Belly's pretty blouse, but if you're looking for a similar style, how about this Rixo top that's near-identical?
Footwear wise, she's wearing the 1915 Inglesa Recicled Organic Cotton DREC in Blanco.

Belly's Earrings, Bracelet & Necklace
All the gold jewelry she's wearing in the show is part of the Catbird NYX x The Summer I Turned Pretty collection. From the Slumberous Light Opal Studs to the Twin Hearts Bracelet and the Diamond Fizz Ring in Sparkler.

Belly's White Lace Top & Denim Shorts
I have no words after watching this episode of The Summer I Turned Pretty - it's the Conrad POV one directed by Jenny Han. It was as amazing as we all hoped, but there weren't as many fashion looks during this extended episode.
The main outfit was this Doen lace blouse and Levi's denim shorts. They've both sold out but I think these frayed jean shorts from the same brand are a winner.
As for the top, I love this Rixo top that's near-identical. This is a celebrity-loved brand and has so many pieces Belly would wear.

Belly's Ditsy Print Swimsuit
In the scene where Belly goes for a swim, she's wearing the Solid & Striped 'Taylor' one-piece which you might remember she's worn before over 4th July. If you're looking for another swimsuit from the same brand, there are so many gorgeous styles to choose from.
If you're looking for a similar style, I adore this Boden one-piece.

Belly's Wedding Dress
When Belly goes wedding dress shopping she discovers 'the one' at the very end of the shopping trip. The dress just so happens to be the floor length ivory Victoria Beckham dress, priced at $1,250.
If you're looking for similar but for a fraction of the cost, how about this AWBridal dress.

Belly's Cherry Print Reformation Dress
Belly wore a cherry-print Reformation dress on the show. Alas, her exact style has sold out BUT there is a newer version and it's super cute.

Belly's Purple Mini Dress
A Dedication Ceremony dinner calls for a fabulous outfit and Belly opts for a Zimmermann Raie dress in a delicious cornflower blue / purple shade. It's - of course - sold out now but do not worry, I've found this amazing dress from Reformation in the same cornflower blue shade.

Belly's Coach Bag & Accessories
If you watch the show you'll know that Coach is an advertiser for the show, so it's not a surprise to see Belly wearing a Coach bag. For the Dedication Ceremony she opted for a chalk white Coach Tabby bag.
If that's out of your price range, how about this Coach bag that's ever so similar but it's 40% off. Wow!
Jewelry-wise, Belly's wearing the CatBird NYC daisy charm on a chain. Right now, it's on sale.

Belly's Daisy Bikini
A day at the beach call for a stylish bikini, and Belly's bikini of choice for series three is the Solid & Striped 'Daphne' bikini top which is so chic and what's more, it comes in other colours. I love it in 'taffy pink' - and think that's so Belly so it wouldn't surprise me if she owned that one as well.
This bikini is described on the website as 90s-inspired and it has underwire cups and adjustable straps which offers support without compromising style. Pair with the matching Daphne bikini bottoms and some denim shorts like Belly.

Belly's Reformation Blue Floral Dress
I have some good news and bad news - Belly wore Reformation but the bad news is that her cream blue floral Analise drop waist dress has sold out. I will say though that this new Reformation dress is very similar indeed. If you're looking for something similar, I absolutely love the Rihoas midi dress which is a real steal.

Belly's Oversized Denim Jacket
Everyone needs a blue oversized denim jacket, especially if you love sitting by the beach when the sun goes down. To get the look, I'd opt for this 90s ASOS denim jacket - you just can't go wrong with it.

Belly's Red Cat Eye Sunglasses
I am kicking myself right now! I recently saw a pair of red cat eye sunglasses and decided against buying them. Big mistake! I'm now super influenced by Belly and her red cat eye sunnies. I'm unsure which brand these are but I've tracked down a very good lookalike by Kate Spade New York (outlet prices) and Nordstrom Rack.

Belly's Denim Reformation Dress
Call it the Belly effect, but her shortened Reformation 'Pennington' dress has sold out but if you love the style, there is a new version with a green floral print. This cool-girl dress has back smocking, adjustable straps, and a sweetheart neckline.
If you're after a closer lookalike, I would probably go for something more like this Mango mini dress - perfect for a coffee date.

Belly's Superga Sneakers
You can't go wrong with a pair of Superga sneakers, and you do you know who loves them? Belly. Do you know who else is a fan? Princess Kate.
