Mischa Barton -- Fly Girl!

Mischa was spotted in New York City yesterday ... letting it all hang out. As she left a lunch date with her boyfriend Cisco Adler, paparazzi caught her with her zipper down.

This poor girl is constantly taking heat for her risky style choices, but we think that her downed fly was not a fashion statement. Perhaps this was an attempt to show the world that some of today's starlets still wear panties ... or she just needed some fresh air.
