Ashley Long is a twenty-something white woman of above average height, with maybe a little more meat on her bones than is currently trendy, but gives her some nice curves.  She has fair skin, blue eyes, and shoulder length blond hair.  While it would be wrong to say she has no sense of fashion, she trends toward practical and simple, as if she had other things to focus on.  It's just more noticeable in a town as image-focused as LA.

As Flex, she wears a tight, pink and black bodysuit, with white boots and gloves and a black domino mask.  While her malleable body lets her subtly change her facial shape, the more obvious difference is that she stretches her hair out into a long ponytail.
