Bachelor Nation Went All Out For Halloween — Check Out Their Impressive Costumes!

Jeepers! Colton, The Bachelor's leading man for season 23, and his girlfriend, Cassie, dressed up as Fred and Daphne from the Scooby-Doo franchise. They showed their dedication to the characters with spot-on costumes and a cheeky impression of the animated duo.

Wells, Bachelor in Paradise's favorite bartender, had an impressive get-up as Freddie Mercury. He rocked out alongside his fiancée, Sarah Hyland, who beautifully dressed up as David Bowie.

Jason and Kaitlyn channeled their inner Ross and Rachel by reenacting the Friends characters' iconic drunken Las Vegas marriage.

Bekah hilariously wins for group costume of the year. She gave herself a starring role on The Bachelorette by dressing up as a leading lady from the show. Of course, the ensemble wouldn't be complete without Chris Harrison or a bundle of (adorable) roses to be handed out.

Hands down, Nick's costume is one of the most creative from this year. He dressed up as The Bachelor's newly announced leading man, Peter Weber, but with a twist. Nick added a bandage to his forehead to remember the clumsy accident the pilot had while filming his season in Costa Rica, which left him with 22 stitches.

Bachelor Nation's self-proclaimed van couple had a Freaky Friday moment on Halloween when they dressed up as each other. Dean wore high heels and a pageant crown while Caelynn went casual in a beanie and accessorized with a toy camper van.

Sadly, John Paul Jones's relationship with Tayshia Adams didn't last long enough for us to see them do a couple costume this Halloween. That didn't stop him from going all out for the festivities, because he absolutely nailed a Ken and Barbie costume with a friend.

Bachelor in Paradise sweethearts Dylan and Hannah looked gorgeous together while dressed up as Danny and Sandy from Grease.

The newlyweds channeled their inner Twilight by dressing up as Bella and Edward from the 2008 movie. Jared was perfectly pale, as a vampire should be, and Ashley nailed Bella's dramatic facial expression.

Arie Luyendyk Jr. didn't dress up for Halloween this year, but his little one did. He and Lauren Burnham's adorable daughter dressed up as a bird and rightfully earned all the attention this spooky season.

Demi, a newly single fan favorite, posed alongside Nick Viall to show off her fun and flirty Hooters waitress costume.

Garett from Hannah Brown's season of The Bachelorette dressed up as the coolest Teenage Mutant Ninja Turtle. He also managed to find the cutest pumpkin from the pumpkin patch for this awesome photo.

Cam brought a pun to his Halloween festivities by dressing up as a doctor and carrying around some pepper. Get it?

One half of the Ferguson twins dressed up as Harley Quinn, while her NHL boyfriend, William Karlsson, pulled off a seriously convincing Joker.

Evan chose to match with his little one this Halloween. They dressed up as a couple of gnomes.
