Five years ago, the fashion industry faced a reckoning over the startling lack of diversity among the models on major designer runways. Reacting to complaints that many shows and magazines included nothing but white models, Vogue, in its July 2008 issue, featured a substantial article that asked, in its headline, “Is Fashion Racist?”

This came shortly after Franca Sozzani, the editor of Italian Vogue, published a provocative issue using only black models and feature subjects; Bethann Hardison, a former model and agent, initiated a series of panel discussions on the subject; and Diane von Furstenberg, the president of the Council of Fashion Designers of America, urged members to be more aware of diversity in casting.

And since then, almost nothing has changed.

The New York shows are as dominated by white models as they have been since the late 1990s, roughly at the end of the era of supermodels. Jezebel, a blog that has been tracking the appearance of minorities in fashion shows since the debate erupted, noted that the numbers are hardly encouraging. After a notable increase in 2009 that followed extensive news media coverage, the representation of black models has remained fairly steady until this year, when they accounted for only 6 percent of the looks shown at the last Fashion Week in February (down from 8.1 percent the previous season); 82.7 percent were worn by white models.

In Europe, where Phoebe Philo of Céline, Raf Simons of Dior and many others have presented entire collections using no black models at all, the opportunities have been even less favorable for minorities.
