Back when the final book in the Harry Potter series, Harry Potter and the Deathly Hallows, I decided to to put together a Gryffindor student costume for the midnight book release.
I'm not very good at sewing, so I tried to gather all the pieces I would need. The pleated skirt was from an animecostume that I already had. I bought a white blouse and a clip-in tie that was close to the Gryffindor colors. I added a gray sweater and black knee socks that I had in my closet. Black mary jane shoes was the last part that I had to buy.
The hardest part of the costume was the robe. I had my black college graduation robe in my closet, and I decided to alter it for my purposes. I removed the zipper, and then hemmed the part where the zipper had been. I got a Gryffindor patch off of eBay and sewed that on to the robe.
The robe was fairly easy to make, and the rest just had to be gathered. For this reason, making your own homemade costume from the Harry Potter universe is pretty easy.
I should note that I did wear this costume toDragon*Con that year, and it was not a good idea because I roasted the whole time I was wearing it. September in Georgia is not a good time to wear a costume with so many layers.
I will be breaking the costume out again for the midnight premiere of Harry Potter and the Deathly Hallows - Part 2 and I'm looking forward to wearing it again!
