How dressed-up do you get for the school drop-off line? Mamas taking their kids to a London school are involved in a heated debate about their attire. At opposite ends of the issue are the "yummies" who arrive dressed to impress with coiffed hair and made-up faces and the "slummies," ladies who stick to more casual clothes and natural appearances. Moms at the London school have pointed to Claudia Schiffer, Elle Macpherson and Stella McCartney as examples of how a woman can dress-up without overdoing it and have even created a list of items that warrant a parent being put on the "slummy" list, including maternity clothes, leopard print, sweatsuits, mismatched socks and dirty clothes.
