B. Darlin sequin lace up back dress

This is a B. Darlin Double Spaghetti strap V neck lace up sequin dress in Blue size 9 juniors or 10 women’s. It is brand new and never worn. I bought it not knowing there was a train on the back and it won’t work for the occasion I need. I bought it non refundable from the store. The fit is very stretchy. I am 5’7” and 150lbs for reference
