What's up with celebrity designers hawking pajamas this season? Just a few weeks ago, Kate Moss released word that her holiday collection for Topshop would include lingerie and PJs for the first time (perhaps partly as a result of her boyfriend, The Kills' Jamie Hince, always stealing hers and wearing them out). Included in the collection is a kimono-style short robe, which was among the first items to sell out, a bed jacket and teddy among other items fit for sleep.

Meanwhile, Stella McCartney just premiered her first-ever lingerie line, which includes its own bedroom jacket by way of a lace cardigan. The collection, for Benton Ltd., includes a variety of lace separates as well as a silver version of Chloe's coveted scallop shorts for SS09. And, the first images of Nicole Richie's soon-to-debut clothing line, Winter Kate, have arrived and the collection is decidedly more bedroom than anything else. Richie is a huge proponent of wearing bed jackets during the day. And from the looks of styles from the line on Richie's site, there are plenty of pajamas ready to double as daywear. Whether or not Richie approves of no-pants (which is how the majority of the looks are styled) for the everyday is unclear.
