Made famous by fraternity houses, the toga has a lot of things going for it. The look is quick and simple, with a whole plethora of easy ways to accessorize. If you want to go all out, you can grab some sandals and gold wreath crowns to look like Greek royalty, or you can simply toss on the toga costume. And all it takes to get the party started while wearing this costume style is to shout the word "Toga!" and repeat ad nauseam.

Depending on who you ask, The Great Gatsby is F. Scott Fitzgerald's masterpiece novel about passion and the great American Dream, or it's a movie starring Leonardo DiCaprio. Whichever version you prefer, there's no denying that the 1920s makes for a great party theme. All it takes is a little bit of jazz music, our flapper dresses, and some dashing suits to make your party feel like the speakeasy throwback you've been yearning for.
