Sasha is a teenage girl of tall height, taller than Marcy and Anne, with a slender build. She has blonde hair tied in a ponytail with a long bang parted to the right side of her head, a beauty mark underneath her left eye, and almond-shaped brown eyes. During her time in training, Sasha's arms have noticeably gained muscle mass due to her intense training.
She now has a visible scar on her right cheek from her fight with Anne on top of Toad Tower in "Reunion", when Grime's dagger cut against her cheek.
