I recently picked up the "French Bourgeois" expression from commentators of Fall 2009 runway shows. The details are very erotic, but in a very clean, demure way. Lots of French lingerie detailing: bras showing off, lace, lots of bows, satin, faux flowers, skin in enigmatic places... But at the same time, she is very put together: over the top jewelry, hair and makeup extremely put together (think chignon). Very seductive!
