When I did a poll a while back,  the majority of people indicated that they were okay with a little non-beauty content. Today I have clothing on my mind, here we are. Also, I've been traveling for the last week and I need to take some more photos before I can post on any of the makeup topics I have planned. This post, then, is basically me thinking out loud (at length, as always) about what to wear this winter - if that's not your thing, I've added a cut below so you can scroll on past if you like.

I'm working from home this year, so the work clothes I bought last year (slacks, nice cardigans, pencil skirts, etc.) are not getting much use these days. Still, I feel slightly gross wearing yoga pants and old t-shirts every day, and all-day pajamas don't do anything to help my productivity. But it's so comfortable! I decided, therefore, that that my work wardrobe for this year is going to consist of leggings/yoga pants, but with long, warm, drapey sweaters over then. That way I don't feel like a complete fucking slob, but it's still relaxed - and if someone comes to the door, they can't tell if I'm not wearing a bra, because layers.

(Speaking of bras, why do they conspire to all wear out at the same time so that you have to spend a fortune replacing them. I need to do some bra shopping as well. My favorite bra for combining comfort and support is the Montelle Pure Plus bra. I'd recommend it if your boobs are wide spaced and/or point more to the sides than the front.)

In my head this working-from-home uniform should be art historian chic (though I deviate from the artsy uniform in that I do wear makeup - I'm not actually an art historian, after all - and I leave the giant, statement earrings for days I'm not staying home). I don't have a tripod, but I tried to take a photo in my mirror of an outfit like this that I already own. Fashion blogger I am not, and it was tragic. Anyway, you can all imagine what a long sweater (tunic or cardigan) over leggings looks like. It's not that out there. I'll show you what I've found in my search today, but I would love additional suggestions if any of you are masters of this aesthetic. I haven't been particularly successful.
