You could also attempt make your own entirely from scratch if you have a good amount of sewing ability and patience.
The first thing you need is your house tie. You may purchase a house tie (striped red and gold, green and silver, yellow and black or blue and bronze/silver, according to whichever house you’re in) for a large variety of prices ranging from $7 to $130. Use your best judgment, see what other people think of the same product, and please don’t use all your money on a tie. Remember that only the part near your neck will really be visible anyway since it’ll be under your vest. The second accessory you’ll need is your pointed black hat. Luckily the hats aren’t specifically colored, and it’s very easy to find an inexpensive black witch hat in stores around Halloween, or online at other times of the year. The third is your wand. Now, of course the wand isn’t going to do much magic, but it can LOOK like it would! There are two ways to obtain a wand. Option one is to purchase a wand, and option two is to Make a Harry Potter Wand yourself. The second option is more work, but it’s also more fun (and less expensive).
