Birdy Grey Purple One Shoulder Dress size large

Selling a size large but pictured is me in size medium. Picture one is before I got the medium altered and picture two is after. I typically wear a dress size 8 so the large is probably closer to a size 10. I bought both a medium and a large to try on for a wedding and didn't return the large in time. Only tried on tags still on. Very elegant and lovely color and fabric very comfortable. No bra built in. Smoke free home.
