Vintage 70s Maxi Dress

Beautiful vintage 70s Maxi Dress! The brand is Lady Blair and I don't see the size, but it appears to be a size 18, the same as most all the clothing items I have from this grouping. It's made of polyester and has long sleeves and a rounded neck. Has a tieback for waist area and zips up in the back, also hook & eye closure. The dress is black with a floral print. I can take more precise measurements for anyone who may be interested!
