Piazza Simpone long sleeve midi dress with pleats, made in Italy

Trendy dark charcoal grey pinstripe long sleeve dress. V-neck, asymmetrical pleating (left side only. Beautiful tapered sleeve with button cuffs. Side zip. Darts for shaping. Approximate measurements when laid flat pit to pit 19 inches length 46 inches. No fabric or size tag- estimate to me a size 10 or 12 but please check measurements. Heavier weight fabric-feels like maybe a wool blend but does have some stretch. Excellent pre-owned condition -no flaws-like new!
