Nicky Visits Paris in a "Pot Brownies" Dress

Nicky Hilton decided to wear a very irie piece of fashion while visiting her sister in the slammer over the weekend.

The item of choice ... a dress appropriately named "Alice B. Toklas." Interestingly, the Alice B. Toklas Cook Book included the first published recipe for "Haschich [sic] Fudge," more commonly known as ... pot brownies. Shabaaa!

Sources tell TMZ that the stoney dress is just one from Nicky's extensive collection of Kate & Kass. Nicky purchased this dress last month at the Sienna Boutique on Melrose Ave. in Los Angeles. Of course, in typical Hilton style, she bought the entire line!
