Bridesmaid/Graduation dress

Purchased this bridesmaid dress at Bridal Debut in Sherwood park. Wore it one time for a wedding. Dress is size 12, has been slightly hemmed to pull the straps up as it was too long when I bought it. I am 5’6, and wore it with 4 inch heels and it touches the ground. Dress has pockets on both sides and comes with a zipper down the back. Dress has been dry cleaned and is ready to wear for a wedding, graduation or any formal celebration. Paid $277 for this. Asking $80 OBO. Pick up in the Hamptons. Non smoking home. Cash only.
