Based on other reviews I ordered 1 size larger than my normal and they fit great.  They look like normal bikini bottoms that actually cover!

I am short and muscular.  I love the fit of these!  They have a draw string and really stay in place!

I got the pink bottoms in size medium.  I am 5''6, 125 lbs and these fit well.  They are a bit tight in the waist, but not enough to be uncomfortable or unattractive.  They are tight enough to stay up while swimming or playing with the kids!  Coverage in the back is good.

Excellent bikini bottom. I opted for this one that has full coverage and it is so comfortable! But what I really like is it''s still lower cut--it''s just that your whole butt isn''t sticking of the side in the back. So, to me, it''s still sexy and cute, but not over revealing. The support and comfort is great, and it has a tiny drawstring in it to really secure it if you want for swimming or body surfing, etc. You probably don''t really need it though since the waistband really stays put if you order the correct size.
--Like my review in the bikini top I bought to match, the only thing I don''t like are the sort of dull color choices. Yes, the pattern is cute. But I really like bright colors for swimsuits and this blue is darker when you receive it. The pink one was too mauve and washes out on skin tones and I''m not in to army green myself.
--Overall though, its'' a phenomenal suit and I will wear it often - mostly during rigorous activities (body surfing, workout bikini at gym pool, etc.).

I ordered this swim as a training swimsuit during my pregnancy.
From the reviews I read, I decided to order 1 size above (Large) my normal one (I''ve always been wearing Medium in my bikinis, Roxy, Billabong, Oneill).
Hummm... It is bordeline too big. As I''ll get a belly in the next few weeks it should be allright, but, otherwise, I would have prefer a Medium.
PS. The quality of the bottom looks better to me that the quality of the top.

I found that the bottoms fit a bit too tight around the legs but other than that I like the style of them.
