Vintage escada silk top

Vintage escada top, says size 40 but not sure if it’s IT OR FR OR EU. Regardless I had it tailored to fit me so please refer to exact measurements of the top. It has a size zipper on one side and lace up on the other side so it is adjustable on the lace up side to make looser or tighter! I’d say this best fits a small! Lining is 100% silk. Length: 14 inches Bust: 13 inches across Waist: 13 inches across
