Sienna Miller sits naked on the edge of a bathtub, holding a phone to her ear and chatting. Her skin is bare, and she’s relaxed as she talks. Then she turns around, giving a clear view of her bare butt, before stepping into the warm water. Once in the tub, she sits topless, her breasts visible above the waterline, still talking on the phone casually. In another scene, Sienna Miller is fully nude during a steamy sex moment with a man next to a crackling fireplace. Her breasts are exposed as the guy tugs her panties down her legs. He grabs her hips and lifts her up while she leans back against him, the firelight glowing on her skin. Later, she climbs on top of him, showing her breasts and a glimpse of her pubic hair as she moves. In a different moment, Sienna Miller lies on her side in bed next to a man. As she shifts her arm, a small part of her right nipple peeks out from under the sheet. In yet another scene, she’s sprawled naked on her stomach across a bed, her bare butt and left breast visible as she rolls onto her side. A group of men stands around her, watching closely—one of them points a camera at her, recording. When she sits up, her breasts are fully in view for a moment before a guy steps in, draping a coat over her shoulders to cover her up. This is from the 2006 movie Factory Girl.

Keira Knightley has a nude scene in the 2002 version of Doctor Zhivago. In this particular scene, she reveals her breasts during a romantic moment. While there isn't a lot of nudity overall, she definitely brings a sexy vibe to the film, and we get a glimpse of some side boob too.
