I love flannel in winter! Plaid flannels can feel a bit masculine to me, which is usually okay, but sometimes not, if you know what i mean. (And I think you do.) So sometimes I look for more "feminine" colours in the plaid (since most flannels are plaid, it seems!)
My current ones are below, but I used to have a great Stewart dress plaid flannel from LL Bean. I would love another flannel shirt with reds or hot pinks in it.
It was Angie who suggested to me that I consider flannel shirts in winter. I wasn't wearing my crisp cotton button downs nearly often enough when I lived in Ontario. The style for me is a slam dunk (as it is for you) yet I wasn't reaching for them and was feeling both guilty and sad (because I missed the style all winter.)
It was all about the climate! I do wear the long sleeved cotton shirts now -- but I wear them spring/ summer/ autumn. And I still like flannel better for winter.
I used to love sleeping on flannel sheets as a child. I still like it when I encounter them. Though we don't own any.
