I purchased this robe for my four year-old nephew, and he absolutely loves it. It's surprisingly well-made, with red faux silk lining and a thick black velvet outer layer. The attention to detail is very impressive; the Gryffindor badge is as well rendered as one on an actual school uniform.
All in all, a wonderfully tactile and durable gift. My nephew insists on wearing it inside the house and out, and it's weathered numerous bumps and scrapes over the last few weeks. Little Harry Potter fans will adore this costume.
