wore this one to a fundraiser/ early evening event. paired with dangly earrings and nude 2 1/2 inch open-toed shoes. voting for "runs large" because the top portion has very long straps and was too loose on the Small. the XS was a perfect fit; the skirt is a little short but still very comfortable just had to be careful sitting and getting out of cars. didn't need to wear a bra. looks great; innocent but sexy without looking like trying too hard. perfect for a night of looking charming and feminine without being over-dressed. my date loved it.
