Lisa Rinna hit a NYC rooftop party on Thursday in her summer yellow Shoshanna dress, cinched at the hem and waist. The latest cast member of Broadway’s Chicago (starring with hubby Harry Hamlin) finished off her look with open-toe wedges, hoop earrings and a white clutch.

Rosario Dawson wore an off-the-shoulder version of the same Shoshanna dress as she shared her sun safety suggestions at NYC’s Bloomingdale’s in April. The Grindhouse star finished off her with dark yellow drop earrings and classic black pumps.

Who wore it best — LISA RINNA or ROSARIO DAWSON?

Tori Spelling (in Alice + Olivia) and hubby Dean McDermott celebrate the opening of their new bed & breakfast Chateau La Rue on Saturday afternoon in Fallbrook, Calif. The couple are taping for the Oxygen Network’s new reality TV show Tori & Dean: Inn Love.

Gotta hand it to Tori’s TV shows for at least having creative twists to them — so NoTORIous and Tori & Dean: INN Love. Bravo!

Tori, 33, is expecting a baby boy later this month with Dean, 40.

Also in attendance at Tori and Dean’s B&B opening were Lisa Rinna and hubby Harry Hamlin, Grant Show and wife Pollyanna McIntosh, and Kelly Rutherford and hubby Daniel Giersch with 4-month-old son Hermes.

Little tidbits: Rinna, Show, and Rutherford all starred on Aaron Spelling’s Melrose Place (Tori did make guest appearances). Rutherford practices yoga with Lisa Rinna and Desperate Housewives star Marcia Cross.
