Just a casual day reading in a bikini 16.
She ditched her flats for a pair of killer black heels and showed off her toned legs in a pair of black and white striped shorts and black shirt.
There were a number of stars at the party, including Jamie Chung, Olivia Culpo, Aubrey Plaza, Katherine McPhee, and Maria Menounos.
Peyton always looks toned and in shape and mentioned that her favorite thing to do is to go hiking.
This is one of Peyton's best looks.
Fans of actress Peyton List can find her hot pics assembled in the image gallery uploaded by her.
