Here’s a picture of my underwear drawers. I put on dark colors in the morning, and whites at night (after shower). I have roughly 65 pairs of underwears.
Below that is a picture of my sock drawers. I wear black socks when I go out, to match dark colored shoes, and wear whites at home. Same goes with my T-shirts. I wear dark t-shirts when I go out, and change into white t-shirt as soon as I come back home. Bleached white linens (pima cotton) give me cozy feeling.
