Im 245 and 5’8 the 1X fit me. I have a small waist and carry most of my weight in my butt/hips/thighs. it still covered my butt. it is pretty thin but not see through for the cost so it’s only worth to buy on sale.

Fit was fire ! Not as mock neck as the picture tho, but still cute ! Pretty long and im 5’11, it went atleast an inch above my knees
