H&M brand size 12, but fits more like a 10. Fits my mannequin well, but not tight. See last pic for mannequin measurments. Dress material has no stretch to it. Button down half way the front of dress. Has 2 front hip pockets and cute little belt loops on the sides & one in the back that forms an "X". Fully lined. Cap sleeves. Bottom back slit. Super cute and multi functional dress! Sexy or formal! I wore it once for only a couple hours.
