There's a story about a fairly famous nautical engineer (involved in spy subs, Woods Hole stuff, etc... stuff people know about but most don't know him or his name) who had a wardrobe that consisted of nothing but light blue button down shirts (both long and short sleeve, depending on weather), navy blue slacks similar to Dockers of a specific brand, and shorts of the same brand and variety, black socks, and a specific pair of leather shoes. All the same brands and types. He rotated the shoes, one pair was new for "formal" occasions, one pair was the "everyday" pair, and one pair that was nearly worn out was the "lawnmowing" pair.
He claimed he didn't have time to worry about fashion or what to wear in the morning. Just grab a shirt (pick long or short sleeved), pants (or shorts if it was really hot), and slap on the same belt, black socks, and whichever wear-level of shoes was appropriate for the day. Packing for his multiple and frequent trips was also simplified greatly.
He supposedly had to borrow a jacket when the Washington D.C. brass gave him some sort of Naval lifetime-achievement type award. Still wore the slacks and the light blue shirt under it.
One trick I learned from his story, and even my wife ascribes to now, is buying all of the exact same socks in white and black... same brand, a big pile of them. Haven't sorted a sock in almost a decade. When they start to wear out, throw individual ones out, when the pile gets annoyingly small, they become shop rags for the garage, and a new large pile is purchased of all the same socks. Lifespan wasted sorting socks is stupid. There's half a drawer of white, and half a drawer of black, and a small section of "special" socks... some low-cut ones for shorts wear in the summer, all the same white brand and type, and a few expensive hiking/wool/specialty socks, in a different drawer.
Once my wife (nurse) saw me doing this, her daily wear sock drawer got the same treatment... her "specialty" sock drawer is bigger/fuller, but 90% of the time, she doesn't have to sort socks either. Just dump them in the drawer. Done.
