Magical music note pinup ModCloth party dress

I love this dress but am too much of a klutz to wear white! Unlined, feels like rayon or lightweight poly. No tags except for one that says 2XL, which this dress definitely is NOT, so I think it may be from one of those Chinese brands that has teeny tiny sizing. Bit of stretch but not a ton. Zips up the back with hidden zipper. Bust: 38” Waist:32” Length:42”
