I like a loose pair of elastic pajama pants. When my tshirts get too ratty for regular wear, they enter the pajama rotation. I hate being naked because I am clumsy, and the thought of my skin scraping the doorframe as I walk by is heinous.
Also cannot stand being in pajamas all day. Unless I’m really sick, I need to put on day clothes for at least a few hours or it’ll trigger depression.
Comfy cotton shorts and a camisole and wool socks. In the fall and winter, I wear sweatpants instead, and if it’s really cold, I throw on a cardigan. All in black so they go well with each other or as part of other outfits. It’s modular and minimalist and I spent way too much time thinking about and perfecting sleepwear over the past decade lol.
But I specifically like that they’re not technically pajamas because, like OP, I feel weird if I’m in pajamas all day. So the bottoms can double as lounge clothes if necessary and pair decently with most of my tops for a super casual look on a lazy day.
I actually don’t own any traditional pair of pajamas, which is all right by me.
