Blue Lace Party Dress Retro Vibes Mid Modern

Lovely little dress in very good pre-loved condition. Substantial blue lace with blue lining. Has black ribbon accent at waist and pretty pleating detail on one side. 3/4 sleeves and zips in back. There’s no brand nor is there a size tag. My best guess is this is extra small but please refer to measurements in photos. Has a mid-century modern to 60’s vibe.
