Paris Hilton is adjusting to life outside jail with some retail therapy.

The heiress, who arrived back in Los Angeles Tuesday after a post-prison trip to Maui, went on a Hawaiian shopping spree this week. The freed heiress hit the upscale Shops at Wailea – the antithesis of the jail commissary – stopping in Guess, BCBG Max Azria, the art gallery Celebrities (featuring works by famous people), the Enchantress Boutique and its new sister store, Fifi & Bootsie.

On two different private shopping excursions, Hilton, wearing linen shorts, a silk top, big straw hat and white sunglasses, spent “a lot” in Enchantress and Fifi & Bootsie, eclectic specialty boutiques that carry 600 different designers between them, a source says.

Her purchases included T-shirts by Brokedown and Hello Kitty, jewelery, candles, a pink leopard caftan by Monique Leshman, a tunic by Gold Hawk, and a princess-themed toilet roll dispenser for $29.

“She was in a really good mood; she’s a sweet girl,” said one observer. “And she looked great. She’s got so much style.”

The shopping spree also spared her the solitude she endured in her single-person cell: Eighty to 100 people followed her around the outdoor mall trying to snap her picture or obtain an autograph.

“She was so nice and peaceful,” said Enchantress/Fifi & Bootsie co-owner Britta Alexandra. “She’s awesome; it was really great to see her again.”
