Sézane Lyna Jumper - Ecru, Size S Main Fabric: 100% Merino Wool This is one of my absolute favorite sweaters from Sézane. I accidentally machine washed it, and while it did get a bit shorter and tighter in the arms, the body still fits almost the same. I still wear it. But if you’re a size XS or between XS and S, it could be a perfect fit! It’s so soft and elegant. Pit to pit measures 18.5 in.
