Nicola Sz Med/lg Black Embellished Front mini Dress

Pre-owned in good condition Tag says Lg but I think this runs small. I'm adding measurments 19" across chest area pit to pit 33" length from shoulder to bottom of dress Dress is more Mini It hits about 5" above the knee. It's really cute on. I wear a med and it fits me. I'm 36 D if that helps. Dress has 3 layers ..1 underliner, a satin main part and a chiffon layer over the front..
