Aida Ivory intricate floral dress

Reposhing this item I purchased from @laurea_p. Loved it, but the dress is too small for me although I wear size 8 usually. It says on the tag it's a size 8, it's a size 6 in my opinion, which is why I am listing it as size 6. Measurements (also see pictures, pls) Width: 15 (bust) - 18 inches (bottom) Length - 37 inches
