Most teenagers can’t drop $2,000 on a dress from one of the designers presenting during fashion week, so a free blog of the shows will have to do the trick. For the first time, Seventeen has tapped five of its beauty and fashion editors to post twice-daily accounts of the behind-the-scenes drama in the fashion tents through photos, video and commentary. A spokeswoman added the editors would post weekly wrap-ups with photos from the London, Milan and Paris collections, as well. And it appears the magazine’s Web-surfing teen readers clearly aren’t doing their schoolwork: Seventeen’s comment field had several posts from readers even before the first blog entry. Meanwhile, the Wall Street Journal is also blogging about news and fashion trends from the shows — perhaps taking another step in increasing its fashion coverage since forming a new fashion and design bureau last year. L. Gordon Crovitz previously told WWD that the Journal readership purchased “more women’s fashion items than do all the readers of the women’s magazines — combined.” So far, the blog isn’t an individual’s vanity case, like most of the species, but instead includes stories that have already appeared in the paper. It also will offer analysis and images of the runway shows in New York, Milan and Paris.
