1950's Masterpiece by Catalina Brown one piece swimsuit. A total blast from the past in very good vintage condition, totally cleaned. today this would work well as a corset style top tucked into a pencil skirt or classic jeans. Back zip, adjustable shoulder straps. Fits like a US 4-6 despite the measurements and weight tag suggesting closer to a size 8, the fabric is lycra and stretches. 

Shoulder Strap 22" Bust 30" Waist 24" Hips 31" Length 20"
