The Trubikini Swimdress: The perfect alternative to a one-piece swimsuit. 

Made of the finest Italian fabric, our Swimdress offers ‘50s style glamour. Wear it by the pool or at the beach bar. On its own, it’s a stylish cover up and tankini top. Pair it with one of our pant styles - we recommend the High Waist or the Classic - and it is the perfect alternative to the swimsuit. With adjustable length and a halter top, it can be worn short or long, for the perfect fit. The underband is very supportive but it can also be worn with the Ultimate Triangle Bikini top.

Proudly made in Great Britain

Our Trubikini Tribe


"This amazing bikini is from Trubikini, they cater for ladies with larger cup sizes like me, but without the uncomfortable underwire"


"I'm absolutely thrilled with it. I love the quality fabric and finish, and removable padding in the bikini top. Basically, it's pretty perfect”


“I absolutely adore my bikinis! Can’t wait to wear them and photograph them on holiday. I love how you can order different size tops to bottoms"

Size Charts


Ultimate Triangle Size Chart

The Ultimate Triangle comes in 8 sizes (from 0 to 7) and caters for over 40 different bra sizes. Find your Trubikini size easily using our simple size chart. It uses the two elements of your bra size to find your fit. For example, the UK bra size 34C would pick a Trubikini Size 2.

Pant Size Chart

All three of our pants come in 6 simple sizes and fit true to standard UK dress sizes. There is a good amount of stretch to the fabric. So we recommend that you select the Trubikini size that corresponds directly to the UK size you normally wear in pants. For example, a UK size 12 would pick a Trubikini Size 3. If you prefer a little less coverage, try the Trubikini pant one size down.

Swimdress Size Chart

Our Swimdress has a lot of stretch to it, which is why we only need 3 sizes. The Swimdress ties at the neck and has drawstrings at the sides which you can use to change the length, so that you can adjust it for a perfect fit. If you normally wear dresses in UK Size 6, 8 or 10, go for a Trubikini Size 1. If you normally wear dresses in a UK Size 12 or 14, go for a Trubikini Size 2. And if you normally wear a UK Size 16 or 18, try a Trubikini Size 3.
