Did everyone start using as loungewear as everyday wear when Britney Spears danced to "Hit Me Baby One More Time" in track pants? Or maybe that happened when velour sweatsuits, the unofficial celebutante uniform of 2004, became popular? Of course, it could’ve been Rachel Roy’s red carpet sleep set or all of Marc Jacobs’ pajama-clad appearances last winter that really cemented the trend in popular culture, making it a thing. Whatever it was, I know this for sure: the look’s lost its shock value. Everyone’s eyes have adjusted.
Now that the taboo’s gone, lounge-inspired clothes on the street are no longer about making a big splashy statement. That just feels too forced. These days, jammies and sweats look best with subtle styling, so no single "one of these things is not like the other" piece stands out. To pull it off, you need just the right kind of loungewear: something simple and understated enough to wear in a myriad of ways. Neutral-colored cashmere sweatpants are a good way to go, as they are both supremely comfortable and match nearly everything. To show you just how versatile the style can be, I’ve included five possible outfits centered around one pair in the slideshow above, each appropriate for a totally different occasion.
