What To Consider Before Getting The Right Harry Potter Costume?

There are a lot of stores – online or mortar and brick – that sell Harry Potter costumes. Let’s check out what you should know before purchasing your outfit. 

Choose Your Character

Whether it is Harry himself, Ron, Hermoine or other characters like Dumbledore, Snape, Voldemort and Dobby, there are unlimited choices of characters you can cosplay on. It really depends on who you want to be. 

Once you have chosen what character to portray, comes the next step. 

DIY First, Buy Later

Let’s say you want to do Harry Potter cosplay for this coming Halloween. Make a checklist of Harry Potter’s details such as glasses, lightning bolt on the forehead, white shirt, black pants, red and gold tie, black robe and red cardigan. 

If you already have these items at home, reuse them. Draw the lightning bolt on your forehead using an eyeliner. Pick a thin stick from your backyard, and there you go. A magic wand!

But, if you couldn’t find any of these items around your house, it’s time to visit the costume stores.

The sizing guidance provided by the seller is very accurate and helpful.”
