      Sydney, Australia

      Style: High Waist Two-Piece
      Height: 6'0
      Usual dress size: AUS 12
      Cup size: AUS A

      I am a 6ft tall woman (183cm) with a size 12 butt, size 6 waist and a 12A bust. I have never found a pair of swimmer bottoms that come up high enough or a top to match.

      I. Have. Never. Had. Swimmers. This Amazing. In My Life. FULL STOP!

      THANK YOU for making swimmers that are cool.
      THANK YOU for making swimmers that fit women who walk planet earth.
      THANK YOU for producing something that I can truly preach about.

      Style: One-piece
      Height: 5'6
      Usual dress size: AUS 10
      Cup size: AUS E

      I have size 10E boobs, a super long torso, short legs and a sizeable bum. These are all things that make trying on swimwear rather painful.

      I got my navy Aplomb in the mail yesterday. I put it on and instantly felt like a GODDESS.

      BIANCA
      Melbourne, Australia

      Style: One-piece
      Height: 5'5
      Usual dress size: AUS 8-10
      Cup size: AUS E

      When this arrived in the post... all the ladies in the office were skeptical... but my god this one-piece is completely magical!

      JESSICA
      London, UK

      Style: One-piece
      Height: 5'8
      Usual dress size: UK 16
      Cup size: UK G

      I always struggle to find swimwear that fits my larger bust but holds tight to my smaller waist.

      Often you find wires, support sections, or a very specific cup size in swimsuits that aren't very forgiving, so it's nice to have a swimsuit that just holds you in perfectly, exactly to your figure - like it was designed for you - without the discomfort of an underwire or predetermined support.

      VANESSA
      Melbourne, Australia

      Style: One-piece
      Height: 5'5
      Usual dress size: AUS 8 top 14 bottom
      Cup size: AUS DD

      Just wanted to let you know how impressed I am with these crazy-good bathers!

      Trying on bathers is mega painful sometimes, and it’s pretty well impossible to get the right ones when shopping online, so for these bathers to do exactly what you’ve said they do - that's awesome! I can’t wait to get a bikini pair!

      SOFIE
      Perth, Australia

      Style: One-piece
      Height: 5'10
      Usual dress size: AUS 10
      Cup size: AUS C

      Could not recommend Youswim enough! I've been soul searching online for years for a comfy, practical, quality, stylish pair of bathers and this one-piece absolutely ticks all of these boxes.

      I spend a lot of time moving in the water - surfing/swimming/jumping around and they not only support me through these times but keep me feeling confident.

      The best part is that you can go straight from the ocean to grab a coffee as they double as a sweet little ribbed one piece. Very happy customer indeed, can't wait for the kini's!

      DANIELLE
      Edmonton, Canada

      Style: One-piece
      Height: 5'7
      Usual dress size: US 6
      Cup size: US B

      I received the beautiful swimsuit last week and was overwhelmed by how beatiful they are. I had a little cry when I tried it on as I've never felt more comfortable in a swimsuit!

      SCARLETT
      Perth, Australia

      Style: One-piece
      Height: 5'1
      Usual dress size: AUS 6-8
      Cup size: AUS D

      I have the Aplomb in white and the fit is AMAZING. I am a size AU 6-8 with a D bust and it offers the right support for my boobs.

      Although the material is super stretchy it is quite thick and holds you in without digging into the thighs and butt. It really moulds to your body! I can’t get enough of this swimsuit, 5/5!

      RUTHIE
      New York, New York

      Style: One-piece
      Height: 5'9
      Usual dress size: US 6
      Cup size: US B

      You have no idea how much I love my Aplomb swimsuit! I always struggle to find ones that fit well because I have a really big butt, tiny top, and a longgg torso - so nothing fits all of it.

      Then I decided to risk it and order yours online (I never order a swimsuit without trying it on) and it fit perfectly! And I feel so good in it! I'll be waiting for the day you release more
