Why get your Halloween costume online? It’s cheaper, you can’t beat the selection and, really, you can only throw together a last-minute Risky Business get-up so many times before it gets old. So use the web, buy your costume early and don’t worry about it arriving in time. Here are the best places to look.

HalloweenAndCostumes.com

The site helpfully presents a number of highly specific categories, including “Alice in Wonderland,” “Gangsters and Pimps” and “Steampunk Costumes.” Poke around and find the perfect superhero costume for the office Christmas party, something a little edgier for Halloween night on the town and something extra saucy for your lady to wear in the boudoir year round.

Pure Costumes
To showcase the newest looks, Pure Costumes conveniently allowing you to browse the 2011 line as a separate category. The site further features a category of couples costumes, so you and your sweetheart can match.

Spirit Halloween
Don’t settle for cheap imitations this Halloween. Get yourself a theatrical-quality costume from Spirit, the perfect place to get a truly outstanding Pirates of the Caribbean, Thriller­-era Michael Jackson or Dream a Little Dream-era Corey Feldman costume.

Costume Hub 
Costume Hub keeps a running list of what’s hot this year, allowing you to jump on the bandwagon or avoid it like the plague.

The perfect place for a guy looking to dress up like Herman Munster or a Civil War General, Costume Hub also features embellishments like makeup and wigs.
