You can become a cute Pooh. The fabric is a thin towel material and cotton, so one layer is fine for summer. However, it might be chilly to wear as a Halloween costume, so wearing a long-sleeved T-shirt or tights underneath would be a good idea. There are no noticeable stains, but there is a feeling of use, such as pilling. Therefore, please refrain from purchasing if you are looking for something like new or if you are sensitive to such things.
