Case in point: Here's Jessica Biel in her mother's curtains.

Jessica is a beautiful (if somewhat brawny at times) girl, but she should've had this dress tailored a bit - off the rack doesn't work for everyone. That whole slouching thing doesn't work either - is that just overdeveloped shoulders, or does she have Justin crammed into that bag?

Counterpoint: The lovely Kate Bosworth in a properly fitting, attractively accessorized shirtdress.

It's nice to see Kate with curves again.The gold belt and flip flops wouldn't work on a dark-colored dress, but the pastel hues in Kate's dress compliment them perfectly. She needs to ditch that black bag, though.

The verdict? Wear a shirtdress that doesn't overpower your hair and skin tones, stand up straight and for God's sake, Jessica, stop wearing your grandmother's shoes.
