This is a wonderful vintage Norma Kamali dark denim dress from the 1980's. This oversized dress has drop shoulder seams, 3/4 sleeves, breast pockets with flaps and is pleated with a cinched waist (no stretch).
The a-line full skirted portion has side pockets and the long sleeves can be worn as 3/4 length, or cuffed. This dress has the Norma Kamali OMO (on my own) label as well as the Giorgio Beverly Hills Label.
Though it is labeled a vintage size 12, we estimate this dress to fit a modern day US size 8/10, but please review the measurements. The bodice is oversized so it could accommodate a larger bust size.
Shoulders: 24 1/2"
Length from shoulders to waist: 17 1/2"
Length from waist to hem: 28 1/2"
Total length: 45"
Sleeve Length: 14 1/2"
