NUNUNU - Melting Mask Collar Dresswere having a bit of a face melt moment, and it shows. this easy, awesome black dress has our melting mask print all over, a highly rebellious take on the smiley face. made of soft, drapey cotton, its longer in the back for a bit of drama, which you can easily offset with a pair of chucks. wear it over a swimsuit during the day, and then throw on a jacket for a seaside dinner. so much yes.
