Searching for a simple, low-cost way to dress up for Halloween? Look no further than Amazon, which is discounting a massive collection of T-shirt costumes that includes everything from Bowser and Toad to Link and Spider-Man.

Keep in mind that none of these products are actually costumes–instead, they’re simply T-shirts with a unique design on the front. Some of them try their best to mimic a costume (such as the Fred Flintstone Big Costume T-Shirt), but most of them simply feature some funny artwork and let you celebrate the holiday without getting all dressed up.

One of the quirkiest products on sale is the Super Mario This Is My Waluigi Costume T-Shirt, which is down to $20 from its usual $24. The shirt is available in a variety of colors, all of which feature an image of Waluigi’s angry face with the text, “This is my Waluigi costume.” Consider giving it a look if you want to show your support for the neglected Nintendo character this Halloween. You can also grab a Bowser version of this “costume.”

Other great costumes include a Barbie ’90s Logo T-Shirt for $19 (down from $23), a Peanuts Halloween Boo! Shirt for $19 (down from $23), and a Grumpy Bear Costume for $19 (down from $23). Be sure to check out the full sale, but you’ll find a list of our favorites below.
