Vintage sizing of 13/14, which equates to about a small/medium modern sizing. Please check all measurements since vintage runs smaller than modern. Also, this dress is dry clean only, however, it was unfortunately washed in a machine which caused the velvet to bleed into the top part of the dress, turning it into a lightly tinted pink color. It was originally white. It looks like it is meant to be pink but it is not. There is also some sweat staining, all of which is shown in the pictures. Thank you!
