i never used to wear sweatsuits of any type, but two winters ago, i acquired a black top and bottom when i needed some emergency layering pieces. i wear them separately, however. i also have my ex's old, paint-stained grey sweatshirt that i'm very fond of because the fleece is worn out and very soft.
my favorite bottoms in the summer is a pink plaid pajama bottom with a ribbon tie at the waist. i wear them with whatever tee i wore in the daytime, or maybe a sheer sleep tee that i've worn a few days running.
i'm also fond of wearing overalls, both short and long. i have a pair of shortalls, two pairs of long ones (one is loose, the other fitted), and a very faded denim one.
i'm barefoot at home or else wearing some soft slippers.
