Like her Jersey Shore costars, Jenni "JWoww" Farley's look is more revealing than refined, so fans were shocked when she debuted a sophisticated makeover on Saturday.

Farley, 25, arrived at the Los Angeles premiere of The Three Stooges in a chic silver minidress that managed to cover up most of her massive cleavage. She paired it with oversized hoop earrings and silver studded black heels.

Her hair was styled in an elegant updo and she opted for soft pink lips and cheeks with a smoky eye instead of her usual heavy makeup.

The reality star and her pint-sized pregnant BFF, Nicole "Snooki" Polizzi, have been shooting their Jersey Shore spinoff show in Jersey City, N.J.

"It's going to be me and Nicole living in a house: our ups and downs, and our relationships with our boyfriends who we love dearly, our families -- who are just insane! -- and our friends who you really don't get to see on [Jersey Shore]," Farley told Us Weekly.
