Italian made chemise slip gown

Very nice chemise by le Donne di Piere, size L USA, but more like a S/M, I think. Stretchy, silky nylon/polyamide with a sheer, stretchy floral lace top. Scalloped edges, darted bust, adjustable straps, 2 small side splits in hem. Excellent condition. The body is approx 25" long; approx 12.5" across the band under the bust....but the gown is VERY Stretchy! Super nice! Going to list as a "M" even though the tag says USA 36L.
