As luxury labels become more accessible, high-end brands must figure out how to maintain exclusivity to avoid losing legacy consumers.

De Beers once swore it would never debase itself by selling stones that had been grown in a lab. Well, that was then.

Dolce & Gabbana is reeling from a self-inflicted scandal and it seems unlikely to go away anytime soon, says Maryland Smith's Yajin Wang.

Buyers of luxury fashion can be passionate about the brands they shell out for. But can they be loyal when the brand becomes so popular that it loses its exclusivity?

Research from Smith School professor Yajin Wang shows that luxury consumption triggers antisocial behavior, but only if the luxury product is perceived as rare and exclusive and is used in front of other people.

In an era of social media, where the internet brings far-flung places closer and makes location an almost secondary consideration, there is a week when being in the right place – New York City – still matters. It's Fashion Week."It is precisely because of social media that Fashion Week has become so enduring," says the Smith School's Yajin Wang.
