This is a handmade baby carrier cover. Made of double gauze material and can be used reversibly. I received this as a gift, but it didn't fit the baby carrier I have, so I'm selling it. It seems to fit baby carriers like BabyBjorn and Ergobaby. (I don't own those types of baby carriers, so I haven't actually attached it.) It has been washed once, but it's unused. Besides baby carriers, I think it can also be used with car seats and strollers.
