Wearing a Size S for the Amelie top and it fits me very comfortably everywhere. The neckline is elasticated with a functional ribbon, and the sleeves are also elasticated but don’t hug the arms too tightly because the bands are on the thinner side and the fabric is so lightweight. Size S feels like the perfect relaxed fit and is my size pick! This would be so perfect for warmer days. The cotton material is incredibly airy and it feels like barely anything on my skin! I love that this shade of berry isn’t too warm, it’s a lovely neutral that matches all your bottoms!
