I wear 257lbs 5'6. I usually buy 1x/2x. I have thick thighs, & butt. My upper body isn't big butt my arm's are, so I usually size up bcz of them. This suit would have been perfect if it were made w/stretch. It's a thick rayon material that has no give. So it pulls at the seems around the arm's & the pants don't pull all the way up in the crotch area like women like, which causes pulling & or drooping

Fits true to size. Maybe a little big, but not much. . I personally went up a size because of recent weight gain. Looks great on. Tailored, not cheap looking. . Can’t wait to wear out!
