Sophia Tolli Alannah Wedding Dress size 20

Size 20 but has been altered down to a size 12-14ish (was 240lbs when I bought it and was 210 at sizing). Altered for 5’5”. I wore the dress for an hour and changed into a jumper. Dress has sparkles throughout the entire thing with diamond like button up back. Full train with button loop to hook. Built in bra within. Paid $2500 with alterations. Looking to recoup something.
