I ordered a few different pieces during the end of the season sale and I love them all. I’m a true medium and found that I had to order different sizes in each piece — in their culottes the large works best for me, in the sweats and sweatshirt I’m a medium, and in the linen tops I’m a small (mostly). I ordered this top and the Rose top in smalls — the Rose top fits great, still oversized and flowy but this top was a bit more fitted. It fits well for me in the shoulders and bust but unfortunately (and oddly) I’m unable to button the sleeves. If I were to order this top in a new colorway, I would try the medium just for the sake of maybe being able to button the sleeves when I want to. Nonetheless, still loving it and enjoy wearing it but I would stick to your true size or up for this one.
