why we designed this

Our Marley triangle bikini tops were designed with comfort and support in mind. What makes these bikini tops such a highly supportive triangle bikini top is the adjustable elastic filled soft ties around the neck that won't cause neck pain. The soft thick and stretchy fixed elastic band adds lift and extra support to these bikini tops. We also made the cups wrap around slightly, because we all hate it when the girls slid out either side. We know you will love this top paired with some cheeky Parker bikini bottoms, Mia bikini bottoms or bottoms with added coverage like the Jayme bikini bottoms.

    Awesome material!

    GREAT material. Thick and supportive. If you're in between sizes, go up a size. I'm a 34B/32C + 4 in dresses - with a wider ribcage - and I needed a medium when I usually can wear a small.

    Great top!

    I was very surprised by this halter top! I have a large bust (34dd) and usually halter tops really dig into my neck and it’s super uncomfortable however this top is completely different. I got a size large and it fits really well without digging into my neck. There’s adequate coverage over the cup area and band is snug enough. The fabric is like butter and very soft!

    I’m more of a small chested girl, and this bathing suit gives me the lift and cleavage I was looking for. I could not recommend this top enough !
