I bought this suit to wear in a triathlon. I have not participated in the event yet, but have worn the suit for practice in all 3 events and I think it will work fine.

I am 5'6'', 125 pounds, 36B bra, size 4-6 and ordered the medium. It is a good fit. The top is not as tight as my one piece speedo and there is a little gap around the top as I swim - it may just be that I am not a full 36B or maybe you cannot get as tight as a one piece. It does support me well enough for a 5k run - probably would not do a longer distance. Maybe a small top would have been better, but I didn't want to order 2 suits.

Fun suit, but watch where the yellow color falls

GREAT SUIT! I love it so much, it's so cute!

I bought this for my 11 year old daughter who does swim competively, but wanted a two piece that would cover everything and not fall down when she's playing at the pool.  Whether it is true to size, I can't tell.  Normally my daughter wears a 14 girls, sometimes a 0 in juniors.  I got an x-small which fits well, plus she probably will be able to wear it next year too.  It's a beautiful suit and she loves it.

The bottom fit properly but the top was a bit loose and felt too big.

I love this bathing suit. i am a thirteen year old girl and a competion swimmer. i needed more bathing suits and i found this one. i fell in love with it when i first saw it!!. it fits perfectly. i havent been in the water whit it yet but by the way this feels it wiil not slip. on the bottoms they have laces like thing so that you can tie it tighter the helps alot. Hope you purchase this for me its fits perfectly i highly recomend this
