At home, if I'm not going anywhere? PJs. I wear summer ones to sleep year round as I generate enough heat sometimes to roast a bird! Or at least it feels that way! I buy bottoms seperately, and am fussy about the fabric. I have some cotton knit, but my faves are the summer ones made of cotton sheeting. They're getting harder to find, so at the end of the season, when I find them on sale, I stock up. The louder and weirder the print, the better. I think at last count, i had close to 50 pairs, but have pared some down.
Tops are camis i get either at Old Navy, or Walmart. I like the basic kind, without any bra. I have multiple colors, and as they are dirt cheap, when they start to look ratty i just replace them.
Going out, usually on weekends or days off, i wear what i call "sweatpants" generially, but are either yoga or lounge pants. Knit, and either long or capri, depending on the weather. Summer, I have some cotton knit shorts, and i wear tees with them,again depending on the temp outside. I like to be comfy. I also have to match, both pjs and tops, and sweats and tops.
