Evening gown prom dress bridesmaid strapless beaded floor length minimalist

Purchased in 2004 at a “Ma and Pa” type bridal store in Sarnia, Ontario (cannot remember the name, sorry!). No brand tag. Option to be worn strapless or with straps which are detachable. Simple sheath style, slit at the back for easier walking Fabric has no stretch Fully lined (lining is sewn directly to the inside of the dress) Lovely beading on bodice, couple of loose threads but easy fix Flexible boning in bodice for added structure Slight armpit staining, no smell but needs a trip to the cleaners. Some light wear on hem see pic Measurements in pics, size estimate 6 (none found on tags)
