Milos Floral Boho Halter Jumpsuit Black

To be honest I’m confused. It’s cute but the fit is so weird. I ordered a large thinking I’d have extra room. It definitely is more fitted than expected. But what I’m the most confused about is the length. I’m 5 ft 1 inch… and they’re like high waters. I thought they would be a similar length as shown modeled. Im wondering if maybe I got a defective piece.
