This is a one-piece dress from HRM (Human Resource Management). I bought it because I liked the navy and white color blocking, which felt very summery, but the length was a little short for me. I wore it 1-2 times, then had it dry-cleaned and stored it at home. While in storage, there are some areas on the white part that, if you look closely, appear to have stains or discoloration that have surfaced. (See photo 5) It's labeled as 100% cotton, but it looks like linen. There is no size label, but it is equivalent to a M-L size. When laid flat, the shoulder width is approximately 38cm, the body width is approximately 48cm, and the length is 94cm.
