Only wore this one time to my baby shower! This is a size small but really I don’t know why bumpsuit comes in sizes. This is so stretchy it could fit any small/medium sized woman. I am 5 foot 5 and 133 normally. This fit beautiful pre pregnancy too but saved it for my shower. I did have it hemmed a 2 inches so I didn’t fall. Please keep in mind since the dress is white and does slightly suck you in, there are two liners to make the dress look flawless so the hem was expensive ($45) in case you buy this new from the website. Wore this with 4 inch heels for my shower. Got so many compliments at my shower everyone kept saying I looked like a kardashian lol.
