This is a jacket shirt from Spell & The Gypsy. Size is XS. I like this brand and buy from them often, but I usually prefer sizes S-M (Japanese M). American sizes tend to run a bit large, and after checking the size chart, XS seemed like the right fit, and it was perfect. I've worn it a few times, and it doesn't show much wear. It's made of thick fabric that doesn't wrinkle easily, making it a very practical jacket. I often see photos of the designer wearing it as well.
