One of our favorite things about having time off for the holidays is that we can lounge around at home in our robe and slippers with nowhere to go, and no one forces us to wear real clothes.
sometimes most of the time, we wish it was socially acceptable to wear pajamas out in public. And it seems that many celebrities feel the same way.
Whether sporting playful PJs at a theme party or donning sleek sleepwear for a red carpet event, stars such as Rihanna and Jessica Alba have made a cozy fashion statement out of a bedtime staple.
