I ordered this skirt recently and wore it for Valentine's day. I ordered a small and I'm 5'3 and about 127lbs. I typically buy small (in Express pants I am an XS if that helps) and this fit perfectly. Just note when you wear it, it is tight and will show every panty line or bodysuit outline. Highly suggest seamless undies with this skirt. I rarely write reviews and I'm happy I ordered this and I will be ordering other colors to go with other outfits.
