Vintage Powder Blue Size 12 Formal Dress Beaded Sheer Sleeves

This is a lovely vintage formal dress -- perhaps a bridesmaid dress. It is size 12, but please keep in mind vintage sizes run small. The left sleeve has a very faint spot and a couple small snags (shown in photos but it is quite faint). There is a faint spot along the bottom hem. There is some mild discoloration inside the collar (not visible when wearing). I have not attempted to remove any of these spots. Chest is about 35", waist 30", shoulder to shoulder 15-1/2", length from back of neck to bottom 52". Thanks for looking!
