Thank you for the information and advice. I did look at some Adidas swimsuits online, but when I checked the body measurement they were going to be way too small.
Hello.....yeah the sizing can be a pain, too small and they just get uncomfortable, especially the straps they can really dig into the shoulders....its so awkward as they are sized obviously not for a mans figure, i always look at the waist size, especially as they are open shoulders. I usually need an 18 in dresses and tops just because my shoulders are wide - annoyingly. So unfortunately I still find it a bit hit and miss on sizing. I'd probably just opt for an 18 when i'm unsure.
