So cute. My 7 year old & I wore this Halloween costume once at a theme park this fall :) Purchased size 7/8 (now sold out - fit her perfectly with no belly showing fyi! Fabric feels thick & silky and the pants are baggy - she said it felt like pajamas!) & has 130cm listed as well Comes with a one size tank of Derpy that I wore with yoga pants as a “Huntrix fan” mommy & me bounding lol. I am usually a size M and this fit great - imho would fit size S - L depending on how loose you like your tanks Purchased for around 90 + shipping for both
