My guess would be lack of self esteem and a need for attention. Walking around wearing those costumes is sure to draw some stares and raise the curiosity of the 'in crowd' that ignored her at school.

Look at her:

This is not the type of girl who gets ignored in school. She was popular and active in school. Then she met this mysterious, brooding, muscular hunk. She became enthralled with his macho persona, like happens with many other women.
