Looks like Amanda Seyfried is getting used to showing a little (or a lot) of skin.

The 27-year-old actress turned heads at the premiere of Lovelace in Los Angeles on Monday, opting for slinky, low-cut dress with no bra on underneath -- giving photographers plenty of ubiquitous sideboob shots to choose from.

The risqué ensemble looked stunning on the starlet, who kept the the retro-inspired look simple with strappy sandals and a smokey eye.

Perhaps it's only fitting that Seyfried played peek-a-boo with her premiere outfit; in the film she plays Linda Lovelace (real name Linda Boreman), one of the most famous porn stars of all time. With several racy and semi-nude sex scenes, the biopic chronicles Lovelace's rise to fame after starring in the movie Deep Throat.

Seyfried was joined on the red carpet by another iconic sultry actress, Sharon Stone, who plays her mother in the film.

They really do look alike, don't they?
