Super cute dress, but unfortunately *just* too small for me, so I'm reposhing. It's a size 38, which according to Sandro's size chart, is equivalent to a US M. I will say Sandro runs a bit small — I am pretty solidly a M for most US brands, but this dress was about 1-2in too tight under the bust. The Sandro size guide is also in the photos. I didn't wear this out, but the person I purchased it from said she wore it just once to go to a wedding. It's in very good condition. Offers welcome. I purchased this previously on poshmark.
