On her blog, 12-year-old Tavi Gevinson posts photos of herself wielding a toilet plunger, posing in a room covered with newsprint and wearing a paint-splattered tutu inspired by Dolce & Gabbana's spring 2008 collection. She's part of a young generation of fashion bloggers who display their outfits for all to see. "Well I am new here," she wrote March 31 in her first post at Style Rookie. "Lately I've been really interested in fashion, and I like to make binders and slideshows of 'high-fashion' modeling and designs."
