The perfect triangle bikini top for A-G cups

The Ultimate Triangle bikini top is the perfect designer triangle bikini top for A-G cups. Made without underwire, it is exceptionally comfortable to wear, even in larger cup sizes. The beautiful binding detail offers great structure and the supportive underband provides excellent lift. Three layers of the finest Italian fabric offer a wonderfully silky and luxurious 'feel'. For complete personalisation, the Ultimate Triangle bikini top comes with removable gold or silver trim and features removable cups.

Pair the Ultimate Triangle with any one of our Trubikini Pant styles to create your perfect bikini.

Proudly made in Great Britain.

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


“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"


"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”

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.
