I am a Master''s swimmer with 3 swims per week.  This suit is too big for me, I ordered a 34 instead of my usual 36 based on reviews, but the style and fabric are great.  When I swam in it it ballooned out, maybe because this is a finer polyester fabric from the Speedo''s I usually wear.  I am tall, 5''9" with a slender build but big chest, so it is hard to find suits that fit both.

It's quite possible that in general arena's swimsuits run a tad bigger. I wear size 32/6 but had to settle for size 28. I like the way the swimsuit fit but a bit more fabric under the arm would've made it a perfect fit. I especially liked that the bust (DD) felt fairly well supported and the swimsuit was appropriately tight.
