It's made from patterns I bought and I choose, using fabric I bought, to my exact measurements, sometimes with other changes to the design such as different/added pockets, a different neckline, button instead of straight long sleeves, and so on.
Sometimes I worry that the results are a little too odd to be thought of as attractive or appropriate by somewhat less eccentric people such as co-workers and strangers, but personally I adore everything. And I have gotten some compliments at work, especially by the college-age staff members.
At first I avoided even buying flannel, because celestial flannel, especially in pastels, is so strongly associated with pajamas. But flannel is generally less expensive than quilting/novelty-print cottons, it's so comfy, and the room I teach in has been cold a lot lately. I decided to go ahead, but make the pieces look as little like pjs as possible. For instance, for the one fabric that I will have a whole outfit made of, the outfit will be a skirt and shirt/jacket instead of a dress (like a nightshirt) or shirt/jacket with trousers (like pjs). And just a shirt, or a shirt over a t-shirt, with jeans--heck, many people wear flannel shirts like that, right? I also picked out very nice metal buttons (very un-pj-like) and had buttons sleeves (ditto, plus can be rolled up when the environment is a bit warmer). I have two flannel shirts so far & did get asked where I get them, in an approving way.
