Yup I've been rockin my two piece as well ! I'm trying to be most comfortable but if you don't want everybody staring at you all day when you swim I'd get a once piece . It's just however comfortable you feel really , I think people just look because its beautiful & they're probably admiring your baby belly ! That's what I tell myself at least .
I just bought a two piece. I could care less what people think of my strechmarks . Growing babies is my super power, :) plus its more comfortable for me than a one piece
A tankini works well and also motherhood maternity stores carry swimsuits that have room for the belly and bust.
I found a regular one piece from Walmart. It fit my pregnant belly just fine. It was stylish too.
Try a tankini. Once you get bigger a one piece won't fit unless its a maternity suit you can get at target. So I got a tankini
