These are perfect for holiday photos! add to any baby holiday outfit or baby Santa outfit. The faux fur is so awesome and fluffy. The bootie is knit. There is no size tag and no brand. I thought these were maybe home made but the fur is too nice and the back of the booties has a tag like attachment. Use measurements to decide fit. My estimate of 3-6 months is just a complete guess. We had other matching family outfits so didn't use these. baby Santa baby's First Christmas holiday photos
