Even though trends change with the seasons, there are a few constants in the world of fashion. Pajamas are one of those constants. While it's something you basically wear in the privacy of your own home, pajama style can run the gamut from comfort-first to fashion-forward. You don't have to go the stylish route, but traipsing around your abode in should-be-seen PJs can do wonders for your morale. Lay-around gear that isn't just yesterday's outfit or a random shorts-'n'-tee combo is so refreshing. PJs are also the perfect thing to add to your holiday wishlist—the kind of thing that you want but may not necessarily buy for yourself. Whether your chill style is to-the-max comfy or party-ready (yep, it exists!) there's a PJ for you.
