ifindmehere,
hi!
i had the 997 first. i got a small (i'm 5'2-5'3 and if i wore a bra i'd be a 34B) and i nearly dislocated my shoulder putting it over my head. i stepped into it but it was just CRAZY to get on and when i did, i couldn't breathe. i cut a lot of the bottom off, making it a crop-top length, and that helped a lot.
then i got the 983 in medium. a LOT better (still have to step into it) but it did a poofy thing at the top of my (hate to say the word...) boobs. so on that one i cut a "V" shape where it poofed and its good now.
yesterday i received my 974 muscle shirt. i got a small because its not billed as a full-on BINDER, per se. i have to step into it but its great!!
