unused wedding dress

i purchased this dress special order, brand new last month from avenue 22 bridal. i ended up finding my dream dress for a really good price and am looking to sell this one now! i am the original owner, never worn, tags still attached and i have the original receipt. it is a casablanca LE106 mathilde. it can be worn strapless but it also has delicate beaded straps that you can attach. i bought it for $1800 all in. i wear a size 6-8 street size. this dress is a size 12. i measured at a 30” bust, 28” waist, and 42” hips, which put me at a 12-14 with this designer. bought to fit my hips and alter the bust and waist. no alterations done yet.
