I have a vision of what the perfect pajamas look like. It comes from the summer after I graduated college, when I was in California doing an acting internship with a Shakespeare company. My friend Kendra spent many of our evenings in a pair of pajamas she had appropriated from some man or other she'd dated in Flagstaff the year before.
They were green and just baggy enough; she looked feminine but comfortable in them. She'd wear the top open with a cami underneath. In my head they're a light flannel - warm but not bulky - though in reality they might just have been cotton.
I have been looking for a nice pair of pjs, lately. Our house is cold enough that a shirt and lounge pants doesn't quite cover it, and I'd like something a bit more put together looking than just wearing a robe around constantly (I tend to change out of my dressier work clothes as soon as I'm home for the night). Alas, I can't find anything worth getting; the pattern is gaudy, they're cheaply made, they're incredibly bulky or too thin, or they're cut for someone who's 5'3".
Perhaps the solution is to buy Colin a set of pjs for Valentine's and then steal them.
