DJT Womens Stripes Lined Up Double Up Tankini Top Sets Swimwear

Ordered a medium which is 12-14. Bottoms are a good fit, however the top bra bit is very tight (and I don't have a big rib cage either OR boobs). Sizing is a bit off and the bikini bottoms a tad flimsy and see through!

The strap broken straightaway when I try to put on >:.(
