for reference I’m 5’5 and I weigh 175. I usually buy a Large because I’m curvy and have a small waist and pretty big butt. I think that this is just made kinda weirdly. it has to fit the perfect body shape otherwise it’ll be too be in one area and small in another. the jacket for me is really tight in the arms, but the jumpsuit is loose in the tops. maybe with a push up bra I’d be able to fill it out more. it’s super cute tho!! I’m still going to keep it but just beware it might not fit.
