i’m 5’4” and 110lbs (at least before this year’s halloween candy hits) with a 32DD chest, and i ordered two of these skeleton onesies: an xs and small.[according to their sizing, the small should’ve fit me perfectly.. but i had concerns because normally i wear xs.]the small:it’s huge. i have a long torso for my height, but my legs are.. kinda short. not super short, i don’t wear petite jeans, just regular, so take that for what it’s worth. anyway, the small was super baggy and long. the sleeves were really long and almost completely covered my fingers. the crotch hangs down weirdly long and baggy between my legs making it kinda hard to walk comfortably.the xs:fits perfectly. it’s cozy & form fitting enough that i’m not slubbin it like some homeless shapeless weirdo. the fabric is also completely different than the small — it’s much softer (like the inside of a hoody) and it’s thicker. the bones are also the same hue white as the zipper, whereas the small bones were slightly off white so it kinda clashed with the zipper.both costumes:they feel solid, very strong and smooth zippers. the bones aren’t peeling off or damaged, good quality. i won’t be zipping the hood up all the way — it’s weirdly pointed? but i really like how it looks open. my only complaint is the zipper on the bottom.. why? i get it for the guys skeleton costume but for us girls it just looks.. odd. i’ll be cutting off the big zipper pull so it’s not so weird.anyway, for my height and body type, the xs is a much better fit. i’ll definitely be wearing this all winter long as pajamas. ?also, this review is prob WAY more involved than necessary, but i wish someone had taken the time to point out size differences & take a few decent pictures. hope it helps someone else!happy haunting!
