I''m crazy about dolphin and ocean swimwear. I think they are especially
good for women with hips and a bust.I wear both a 38 and a 40--depends
on if I am doing exercises in the pool (will wear the 40), or if I plan to swim
a mile, then I tend to wear my 38''s--as it is a bit tighter and I really stretch when I swim (Total Immersion stroke--great for long distances--to see example of it go to U-Tube) the 38 makes my not very sleek 64 yr. old body feel sleek---it also could just be my own perception. If Dolphin had a 39, that is probably what I would wear which is why both sizes fit..I am 5''2" 150 lbs wear a 14P jeans, the dolphin (and Ocean ) suits, cover
what I want covered--no need to pull at anything coming out of the water, etc. If I get a dolphin suit that is polyester, I always get a 40, because polyester has less stretch.. Hope this is helpful to other swimmers my size. I also feel great wearing it on vacation. I have always gotten black and it is very colorfast as I swim almost daily at our Y.
