You were planning to spend Halloween sans costume and at home alone with a mountain of candy and a stash of Netflix's goriest hits, played at high volume so as to drown out the sound of Snickers-stained fingers jabbing at your doorbell.

But with last-minute party e-vites clogging up your inbox, the urge to socialize with the other goblins has won out. The only problem? There's no way in hell you're dropping a Benjamin on costume rental, and the local party store's selection has been whittled down to two lame contenders: slutty Smurf and a cow costume built for two. Now that's scary.

The good news is that you can dig up a creative costume using what's lurking right in your closet and makeup bag. Here's how. (If none of these ideas work for you, try Refinery29 -- they've got tons more hilarious ideas for last minute costumes.)

The Ghosts of Crappy Weddings Past
You're no Katherine Heigl, but you do have a hideous bridesmaid (or prom) dress or two still haunting your closet, right? And is there anything more spine-tingling than a floor-length, lacy sea-foam gown with a matching bonnet? We think not. Throw it on, and go as a tortured bridesmaid; add some fake blood and go as a dead bridesmaid; or accessorize with a sash and some specs and go as Sarah Palin, Alaskan beauty pageant contestant. Just don't admit that you once actually loved that prom dress.

Meet Your Maker -- er, Makeup Artist
Skip the monster mask and visit, where the brand's visionary makeup artists have assembled a bevy of dramatic looks, from amphibian to robotic to alienesque. Either attempt the step-by-step instructions on your own, or take a printed copy to a MAC beauty counter and let the pros have at it.
