Thank you for viewing. It's a free size, but the waist is a bit large. I could adjust it with the drawstring and wear it from early pregnancy to full term. There's some twisting of the elastic in the waist, blackening around the knees and hem, and fraying at the drawstring holes, but the fabric feels nice and it was very comfortable to wear. I plan to ship via Yu-packet Post. Please consider purchasing if you understand that this is a used item. ♩
