BNLsMOM!!! That would be... just yikes while depressed! It's hard enough when one isn't!!! And to add to it, bathing suits run ridiculously small. And I say this as a very small size wearing person. Can easily double the size (triple? can't remember, it's been awhile) before I even get close to fitting in it. It's ridiculous.

Like QueenAccountant, I'd recommend an alternate approach. I went with a pair of... guess they'd be called river shorts. Thin nylon that dries very quickly -- more quickly than traditional bathing suit material actually. (And they have built in undies! ) And on the top, a colorful exercise bra/top. It's both. But for more modesty, one could go with the same kind of thing in a top with built in bra from the exercise section. They're nylon too.

(Kind of related. I refused to even look at regular bras for 20 years, always just going with the exercise type. Not because I like them though! But because it really set me off one time finding one that fit and it having a pic of seen pre-teen on the tag!!! I was furious at the assumption. I was a full grown adult thankyouverymuch! It traumatized me enough that I couldn't even try without crying and running out. Ugh.)
