H&M summer dress

This is so cute! I bought it second hand without trying it on. Definitely true to size but no give and I’ve got a big ol’ rump, so it doesn’t fit me. Better for petite frame or flat butt ladies. Adjustable straps, 16” pit to pit, 27” waist, A tight 37” about where your butt will be. 30” from the top of the body of it to the bottom hem
