Baby Santa Costume & Knit Hat Set For Newborn Photos Used once for a photoshoot. Born at 2500g and 46cm, it was worn 14 days after birth, and I was able to take a photo like the first one. It was a little big, so I think it can be worn by babies up to around 3500g. I don't see any stains, but it has been worn, so please consider purchasing only if you don't mind.
