Real Women, Real Results

As someone who has struggled with body image my whole life, the little girl who decided she needed a boob job at 12 years old, who stared at her friends c cups and was always jealous how they always looked so good- GET THIS BIKINI. i have never felt so happy looking at my tatas in the mirror. im an A-small B cup with a wider chest and flat sternum and this bikini top has made me feel so sexy and happy with myself. i’ve literally never been so happy in a bikini top in my entire life in my senior age of 23. if you’re considering it- please do it. you will not regret it.

I just bought Flatbaby swimmers and all I can say is oh my god. I don't know what sorcery this is, but the pair I purchased from Flat Baby.. the material and comfort is incredible. And when I look in the mirror at the side of my boobs, they don't look like a push up bikini.. my boobs look so natural and so real.... SORCERY!! My friend had bought the baby pink swimmers size XS and the cup was too small for me, so I bought S (I am a Bcup/C cup) and they were perfect. Can't wait to buy more designs and colours you've got yourself a dedicated customer forever!! 💖

Jacky B

Two words: game changer! Bikini shopping has been a nightmare for me. After 2 babies and explant surgery, my itty bittys were left deflated and everything gaped. This bikini lifts, supports and brings the girls up and in for maximum boobage, with no gaps! Holy grail!

Nienke C

Innovative and great quality! I wanted to say this is the first bikini I’ve wore that makes me look and feel this good!! The girls sit great. Your products are designed perfectly, and give the perfect push even a push-up bra can’t achieve. Really appreciate the quality and detail of the bikini material, and also the level of work that goes into the design of the bag!! Worth every penny ❤️ I HOPE YOUR SMALL BUSINESS CAN CONTINUE TO GROW!! I’ve already recommended your brand to many of my friends who will be expecting to order :))

Alice

I had a boob job and after kids I decided to have them out not realising I’d be left with nothing. Being flat now and a bit broader then most I have been struggling to feel feminine in a bikini. But this actually makes me look like I have some cleavage and it’s top quality also. In love! 😍

Nina

Well where do I start. For 42 years I have never ever liked going to the beach or to the pool due to having itty bittys. I guess I just wanted to say thank you. Thank you for creating something for us girls. Instantly made me feel more confident and happy to go to the beach this summer.

Teneale R

I just wanna say I got mine today. I am a 10AA/8A and it is amazing!! Thanks so much for making these. I was suspicious at first because I’ve tried so many push up bikinis that don’t sit properly. Even the ones that claim to be for small chests don’t work for me because of my small size. But this is 10/10. The quality was also much higher than I expected. I will be back for more colours and styles when I have $$ 😍❤️

Jodie

This is the first time I’m actually excited to wear a bikini, I bought the pink buttercup top and I can’t believe the difference it made in cleavage. I have never had swimwear that made such a noticeable difference it boosted my confidence straight away!

Felicity R

Wow, for the first time, I’m excited to flaunt my chest this summer! 😍 I’ll definitely be buying again and highly recommend this shop to all the small-chested ladies—it’s a total game changer! 👏

Tania P

This swimsuit is great for girls with small chests. Normally, I don’t like wearing push-up bras because they usually leave a gap between the bra and my chest.This is my first bikini, and I absolutely love it. It makes my chest look close together and naturally shaped, which boosts my confidence a lot.

Tarika P

Finally feel comfortable in a bikini!!! Great quality too.

Olivia H

Honestly I’m shook at the boost!!! Just found my new favourite bikinis for this summer. Not sure how I have any cleavage at all but I do with the bikini top. The personalised note was super sweet and quick shipping. Love supporting small businesses. Highly recommend flat baby swim!

Venessa T

Your bikini tops really are wizardry!! I think I stared at my chest in the mirror for a good 10 minutes because I have literally *never* seen cleavage on myself before until now, haha. Thank you for supporting the “IBTC” and I hope you go far with your small business!

Gena C

I have never had bikinis that make me sit so well!! They are the most flattering bikinis I own & I cannot wait for the warmer months to hit, thank you so much😍everyone needs a pair

Ebonye M

I love it! It definitely makes a difference!!

Bella M

I just bought this swimsuit and I love it. It’s SUCH good quality and really does make my boobs look great! The business owner also hand wrote a thank you note! Really made me understand how important shopping at small businesses is 💕

Lottie R

Great quality and very flattering. I’ve had a bilateral mastectomy and this bikini top still gives the impression of having boobs. So happy!

Melanie R

I’m so in love with the Lily swim suit. Since dropping fair amount of weight way to quick and loosing my boobs this swim suit has made me feel confident and comfortable to go back to the beach this summer. And the before service, helping choose sizing, fast to get orders shipped. Thank you so much 😍

Krystal L

Very happy 😊 My bikini came so quickly, it fits me perfectly and the push up is amazing. I don’t feel flat chested at the beach anymore and it’s boosted my confidence! I also send an email enquiry which was answered so quickly even over the Christmas period. Great product great service. Can’t wait for a restock so I can buy another colour in my size 😊Thanks flatbaby!

Milly H

Highly recommend for ittys. I am blown away by the fit, style, and quality of this brand. I absolutely love the Lily top, my flat chest (and I mean flaaaat) has never looked better in a bikini. The shipping was super fast and the extra personal touch with the card made this purchase that much better. Couldn’t be happier.

Jasmine R

Game changing for the itty bitty committee. Never have I been more excited to try swimwear on. I’ve always hated having to worry about how I looked in a bikini, but the ones I ordered from Flatbaby are have put my stresses at ease. The sizing guide provided got me initially worried about whether it’d be too small, but as suggested the xs was a perfect fit. I’m glad I gave this a chance, money well spent. The material and designs are very cute.
