Early on in All About Nina, Mary Elizabeth Winstead is shown topless in bed. A blanket is covering Mary’s breasts but you can see a bit of nip peeking through the top. Mary then sits up and shows her breasts briefly. Then there’s a montage where Mary is working on her routine while wearing only boy shorts. Most of the time Mary is shown from the front with her breasts out of frame or from behind when she’s facing away from the camera. However, you do get a couple of glimpses of Mary’s breasts from the side as she paces around.
About half way through the movie, Mary shows her butt very briefly as she turns around. Then we get a couple of partial views of Mary’s ass as she is bent over a sofa, gets eaten out and then has sex. Mary is then shown in bed and we some left sideboob. Possibly more but the scene is pretty dark and the guy’s shoulder is in the way.
Around an hour in, Mary wears a slightly see through white tank top.
And near the end of the movie, Mary maybe shows part of her ass as she is riding a guy.
