I’m 26y/o, 5’3, 129lbs, 29”-ish waist, size 7/8 jeans (sometimes 9), 34D/32DD bra (38” bust), M in most tops & bottoms, 39” hips. I got this in a L thinking it wouldn’t be too tight but man, it’s still difficult to squeeze into. The material is not like a T-shirt, it’s almost a thick knit like you’d imagine a rectangle strapless bandeau bra to feel. It’s sort of stretchy but it’s a denser knit so not super stretch. I find the shoulders are a bit tight and the cut around the neck is odd. Other than it running small, it’s really cute! The look is adorable. I’d recommend it but size up 1!

The body suit is stiff. It's not stretchy at all like most bodysuits. But, it is cute once you squeeze into it. True to size.
