7 last-minute Halloween costume ideas inspired by pop culture

Halloween is this weekend, so there's still time to find a fun costume. If you're short on time, pop culture can provide inspiration with minimal effort. Here are seven ideas to be the smartest person at the party without much prep.

First, channel the minimalist tech-bro look of Elizabeth Holmes, founder of Theranos. Don a black turtleneck, dress pants, a messy ponytail, and red lipstick. Add Nathan Fielder's blue crewneck shirt over a white t-shirt and black over-the-ear headphones for the perfect blend.

Next, be Kelly Clarkson and the magic shop bird from X's viral exchange. Wear a yellow t-shirt or sweatshirt, baseball cap, and jeans. For a cute couple costume, have your partner be a yellow bird with a $15,000 tag.

For fans of the Amazon Prime show "Off Campus," dress as Briar University's hockey or magician characters. Complete the look with leggings, jeans, a white dress, bunny ears, and a cape for the duo's party scene.

If you're into horror, channel Nikki from the "Freaky" ending. Wear a red-and-black animal print halter top, black shorts, and boots. Add a broken beer bottle and fake blood for extra effect.

For a modern witch, print an Etsy logo on a shirt. You can even take a page from the book "Your Turn: Out with the Old, In with the New" and add a taser for extra style points.

Finally, for Backstreet Boy fans, go all white. This simple look is perfect for the 25th anniversary of their 1999 album "Millennium." Have fun and enjoy the holiday!
