Can anyone help me with their sizing and general experience with Salvatore Piccolo shirts? I'm generally a small in most brands, medium in super slim brands like Spurr/BoO, 14.5-15 US (38-39 EU) in dress shirts, i.e. 39cm in Mastai Ferretti if that helps. They seem to have numerical (neck) sizing and standard (s, m, l, etc.) sizing so would be curious on both. I'm thinking they are super slim so I'd be a medium or 15.5, but don't know.
