Either designers are extremely tired and dreaming of sleep, or they’re really becoming workaholics and don’t have time to change from their sleepwear to daywear. Pajama pants made a huge splash on the runways for Spring 2011. Styles include matching printed tops for a pajama look from head-to-toe, and more wearable options such as the slouchy white pant from Michael Kors. These styles look incredibly comfortable but may take a little courage to actually wear them out in the real world. Check out the runway looks below for ideas on how to incorporate the right style into your wardrobe next season.
