Paris Hilton Seen Last Week Costume Shopping in Costume.

Never one to step out of the house in sweats, Paris Hilton donned a barely-there sailor costume while Halloween shopping last week.

The blond heiress, who recently launched a Marilyn Monroe-inspired perfume, was snapped by paparazzi while shopping at L.A.'s Trashy Lingerie shop, which stocks items like the $400 Alice in Undie Land costume and the naughty lamb-clutching Bad Peep outfit for $350.

 

Although most folks don't shop for Halloween costumes while wearing a costume, Paris Hilton did sporting a sexy white-and-navy-striped bustier, navy hot pants trimmed with brass buttons, fishnet hoisery and a jaunty sailor cap while she scanned the store's aisles from behind her oversized shades, holding a few keepers in her hands.

Knowing how much the socialite likes to party, it's no surprise that she couldn't wait until this weekend to start celebrating the holiday -- or that she'll need more than one costume for the halloween occasion.

As long as her tricks and treats are of the legal variety, Paris -- who pleaded guilty in Vegas last month to misdemeanor drug possession after a cocaine-related arrest earlier this year should be able to stay relatively incognito and escape making negative headlines. Hilton is currently on probation also mandated 200 hours of court-ordered community service and any violation will land this sailor in the brigg.
