/cgl/ - Cosplay & EGL

So I need advice gulls, this was one of the first dresses I bought, paid for a SS to order during the preorder period, the whole jazz.
I wore it a few times and it’s just, sat in my closet. I tried selling it once but it didn’t sell. I think my issue is it’s not particularly flattering on me, a mix of being a bit too small everywhere and being a higher waist cut. The waistband comes right below my boobs and makes me look fat, I feel. I’m also not in love with how massive the neckline lace is and also how the colours are more muted in person than in the stock photo.
Do I try and sell again or keep it, i’ve come to terms that I’m never wearing it again as it stands, but i thought if I chop the top of and convert it to a skirt I would wear it more often. I’m confident in my sewing abilities that i won’t just ruin it, but I feel kinda bad messing with a perfectly good OP by cutting it to pieces.
Thoughts?
