Chava Studio makes made to order clothing. This is their partial button up polo shirtdress, made from a fine oxford 100% cotton cloth by ALUMO, a Swiss cotton company that makes beautiful, small batch, luxury fabrics that are all certified Oeko-Tex STeP Level 3. Sold as small/medium but I wear an XS, it’s supposed to be oversized for a more casual, breezy look—could fit XS, S, or M. Pristine like new condition. Tried on once, never worn otherwise.
