Ninja Costumes

Grab your samurai sword and put on your stealthy Halloween costume. With Spirit Halloween’s selection of adult ninja costumes, protect your true identity from your mortal enemies as you fight to the death (or just to the party). Even if you didn’t learn exactly how to be a ninja from a sensei, we can help you pick out the best ninja Halloween costume that will definitely earn you “Best Dressed” at the Halloween party. For women, a ninja jumpsuit costume will hug your curves in all the right places and may even work to your advantage by distracting your enemy with your looks. And don’t worry, guys. Show off those muscles in a cutoff ninja costume. In a sleeveless tunic and face mask, no one will be able to tell who you really are, but your muscles will tell them all they need to know: STAY AWAY. Don’t want to show off your arms? No problem! In a full-length, hooded ninja Halloween costume, no one will be able to see anything except for your eyes. Any adult ninja Halloween costume will look even more authentic by carrying around a toy samurai sword everywhere you go.
