Vintage silk Lanvin dress sz M

Unbelievably chic Lanvin sheath dress. Made in France!! Lovely black 100% silk fabric in excellent condition. High neck in front and open plunging back for a dramatic 80s does 20s effect. Hits a little below the knee. Labeled a sz 42 - a medium on the smaller side. A little tight in the hips for me and I am typically a 40 in euro dress sizes. 🖤🐈‍⬛
