⚠️ Please allow 10 days for shipping. This is a skirt for a parent-child matching outfit that I purchased here. It originally had no tag, and was labeled as size 80 for the child and M for the parent. It's 100% cotton and cute, but since this was my first skirt, I only wore it once! So, it's in good condition. Although it's size 80, a child wearing size 90 can definitely wear it too. It's navy, but it looks black in the photos... It's navy and white. I'm also selling another parent-child matching outfit from MUJI. Discounts for combined purchases are okay.
