Or at least they've been getting some more face time in the fashion world lately.
The pajama trend started with artist/director/interior designer/pajama-wearing extraordinaire Julian Schnabel. He enjoys wearing silk pjs out in public so much that it's become his "look." His current wife, Olatz Lopez Garmendia, makes them and (lucky for us!) we can purchase and wear them to red carpet events just like Schnabel.
Dolce and Gabbana solidified this trend with their 2009 Spring RTW line:
Althought Schnabel and Dolce & Gabbana's pajama outfits are an improvement over Hugh Heffner's iconic pjs and smoking jacket look, it's comforting to know that the trend of wearing a complete pajama set in public won't spread beyond the wardrobes of over egotistical men with too much money. (If you think Heffner's playboy mansion is over-the-top, check out Schnabel's Manhattan palazzo).
