Black and purple high-low formal dress

Gorgeous high-low dress, the bottom is a deep purple and the top is black with some sparkles along the very top. This dress would be perfect for homecoming, prom, or any formal event. It's only been worn once and is in perfect condition. The tag says the dress is a small, when I got the dress I was a size 2 and it fit great, the material is stretchy so I can still fit it at a size 4
