Herve Leger Liza dress Rose Pink XXS

Super lovely Herve Leger Liza dress. Bought it from OUTNET for a wedding, which was cancelled due to the pandemic. I have removed the back tag but it was never worn. Tried it on once at home and kept in the dustbag the whole time, just thinking that it's the time to find it a better owner. It's sold on YOOX now at about 1000 usd. Tags, guarantee card , and dustbag included. I just want to recover the initial cost (395).
