Dress is cotton/linen with lace insets and openwork. Sleeves and waist have Mother of Pearl buttons. Back and high collar neck have hook/eye closure.
I purchased this antique bridesmaid dress from Magpie Antiques in Carmel by the Sea, California. Since purchase, has been on display for a couple of years, and then in storage for the last 20 years.
In excellent condition given its age. Some small age stains and a few minor separations at the seams, see last 4 pictures.
