Floral leggings size M but listing as a S

These leggings are DEFINITELY not a medium, they're a small possibly a x small. I'm a size 3 and I don't have a butt or anything ( I do have thick thighs though) and they barely fit. They're super cute though and I have worn them a few times. They have 2 tiny holes from the tag being ripped out on accident, but most shirts will cover that anyway
