LONDON -- Sure, you could stick on sexy cat ears or a white sheet with eye holes and call it a day.
Or you could hire a magnificent period costume made by the finest designers in the theatre world.
Britain's National Theatre is one of the world's premiere theatre companies -- known for its period dramas, Shakespeare productions and contemporary plays. As such, they go through a lot of costumes -- which go on to live second lives in a rather magnificent warehouse space in south London.

"The costumes are custom-made for the actors and they can go back 20 to 30 years," she said.
Every costume has sewn inside it the number of the production and the name of the actor who wore it.
"So there's the occasional B. Cumberbatch," Hobbs said.

For Halloween, people often already have their makeup in mind, and they want to be some sort of zombie. That means the period costumes are hot items.
Other popular trends are 18th century, voodoo and Day of the Dead. "Classic gothic looks are always popular, " Hobbs said.

"We get lots of requests for astronauts," Hobbs said. Space fans, time to submit your scripts to the National Theatre!
At the warehouse, the racks are organised decade by decade, starting with Medieval -- perfect for your Game of Thronesreenactment club. They go through the 1990s ('90s prom, anyone?) and various other categories.
But our favourite "category" was the area for the costumes that just didn't belong anywhere else.

You can either browse on your own and select a costume, or for an extra fee one of their experts can help you.
The hire prices are determined by item. A full outfit will cost about £80-£100 ($98-$123), plus VAT. You can also hire individual pieces, or just headgear. The minimum spend is £15.
As the costumes are custom-made for the actor, there's not much choice when it comes to size, unfortunately. For men the costumes can go up to about a 42/44 chest and for women about a size 12-14.

There are fees if you do irreversible damage to the costume, but for superficial stuff, the wizards in the costume shop can probably fix it for a reasonable fee. Just be careful with the fake blood.
"Fake blood doesn't come out, no matter what the package says!" Hobbs said.
