Beige Off The Shoulder Maxi Dress Sheinside

When I received the dress I was pregnant and in the middle of moving. By the time I tried it on, it was tooooo tiny for me. Plenty length, but not enough waist space. Tried to see if I could return it for a large, I've past the return policy dates and they also sold out of this dress in the beige color. :( I'm planning to get the red one in the same design but I need to sell this to get the money for it. :) -According to the site, these are the measurements. Bust:80cm Waist:66cm Length:155cm
