Do you cringe when you hear the term "mommy jeans"? Is your hair the same style (and color) it was when you were in high school? Maybe playing it safe isn't so safe after all. If the clerks at the grocery store are all calling you "ma'am," it's time to bring in the heavy artillery and consider a makeover. Watch your tween parade around like Cinderella at the ball. She wouldn't be anxious about sporting sequins on her collar or asking for a pair of ruby slippers to wear to the school dance. Life is short, and sticking with neutrals, wash-and-wear fabrics and sensible shoes can get old -- before you do. Live a little.
