Rare Vintage Betsey Johnson lace coat 10 (fits like a 6) worn 1x black & blue

In PERFECT condition, this lace “coat” is meant to be worn over a LIB to let it shine. Size 10 but the mannequin is a 6 and fits it perfectly so listing as a 6. See pics for measurements. Snaps in the front if you want to wear it closed, but can be left open as well. Minor stretch but I wouldn’t count on it as the lace is delicate Smoke free home
