Since there was the possibility of snow on Halloween, I thought The Girl should probably have a Hogwarts school robe for her to wear with her Hermione Granger costume. She wasn't about to argue about that. :)
Though most of her costume was based on the first two movies, the robe we wanted is actually based on Harry Potter and the Prizoner of Azkaban... mainly because we like the additional pop of color from the lining.
I found a free pattern on BurdaStyle. Since the pattern was created for adult women, I adjusted some of the measurements to fit a smaller person (hood length and height, sleeve length, robe height and base width). I do wish I had kept the hood height a bit taller. The pattern says 16" for an adult. I made it 13". It fits her just fine, but if she stands up straight with the hood over her head, it looks like the hood seams are straining at the shoulders.
The robe is made from polyester. I thought the drape of the fabric turned out nicely. The lining is a knit polyester so it's much softer (the sleeves and hood are fully lined making the fabric more comfortable against her skin).
The patch was part of a 3-pack I found online back in September. There were actually patches available for all four of the Hogwarts houses.
We thought a wand pocket would be a handy thing for a witch to have so we added one in (the pattern doesn't include it). After having The Girl try on the robe I think it would have been better to have the pocket set back a little further - closer to the side seam. As it is, sometimes the wand wants to poke out the front of the robe.
This was a fairly quick project. I started it one evening and finished it the next morning. It would have probably gone smoother if my sewing machine hadn't started misbehaving. It started throwing the thread and bobbin thread kept knotting up. I couldn't seem to get the tension right either. It was my grandmother's sewing machine. It may be time to replace it. But the robe did get completed and I have a VERY happy Hogwarts student ready for Halloween.
I think she'll make a very good Hermione Granger.
