I think this girl looks like Lisa in many ways ! She's a slim cute preppy girl and clearly loves to wear ultra loose and low cut flats that just can't stay on her feet ... You can see how she is perfectly used to wearing such loose slip-ons. She knows they instantly drop off her heels as soon as her feet are off the ground (and doesn't even bother to stop them from slipping off), and walking with her ballet flats popping off her feet with every step is just a natural thing for her !!! What kills me with this kind of girls is that they usually love so much their loose shoes that they will wear them no matter what, even if it means walking a mile with those unkeepable flats and stepping out of them accidentally several times in front of people !
