Yvette Paris Dress 4 Womens Vintage Black Sequin Lined Halter Sleeveless 38. Condition is good pre-owned vintage.
Approximate measurements are in the pictures. Mannequin in the pictures is a US size 6 (modern sizing) and this doesn't zip up all the way on the back, so this would work best for a US size 2 or 4 in modern sizing. Exact decade is unknown, but I suspect it is from the 1970's.
