I recently made a Harry Potter robe using Simplicity 8723. I wore this to a couple of halloween events but I’m sure I’ll be wearing this anytime of the year. This pattern is great includes robes, sweater and tie in child and teen sizes XS-L and adult sizes XS-XL. The pattern runs large, I made a small and it was a little to big. I’m 5’4″ and 120 pounds just to give you an idea. I didn’t size down because my children, now taller than me, might want to wear it sometimes.
I used black gabardine and stretch sateen in biking red for the facings and lining both from Joann’s. I bought the iron on appliqué patch at the Wizarding World of Harry Potter store in Orlando a few years ago. I wanted to buy the robe but for a $120 I was like I can made that for half as much. I expend around $50 without thread that I already had and the closure that I removed from a cape I made a while ago.
The only modification I made was adding lining to the sleeves. I wanted to line the whole thing but decided not to since I’m planing to wear it next time I visit Universal Studios. Overall this is a very easy pattern and great for beginners. I definitely recommend it just don’t forget to size down.
