Long Black Lace Prom Dress- Sherri Hill look-alike

Size 4-6 (it's a 6 but fits more like a 4) Fits almost like a mermaid gown. Never been worn. Purchased for $280, selling for $170 (Sherri Hill version around $450 I think??) The only difference is there a little less contrast between the nude and black parts of the dress, so basically it's just darker overall, especially the midsection and above. I'm 5'7" and the length is long enough for me to wear it with 4 inch heels. I only didn't wear it because I found another dress. No problems!
