A one-color wardrobe

Simple green…

Hiromi: I have to ask what’s with all your clothes being green? You have a desire to be a tree? 
Jiro: Ha! No secret pact, simple strategy. Fewer choices in the morning means less time wasted deciding what to wear. I wake up, pull on my green gear, no hesitation, no second thoughts.
Hiromi: Is picking a shirt color really that stressful? 
Jiro: It’s not about stress—it’s about efficiency. If my wardrobe is just green, there’s no room for unnecessary decisions. 
Hiromi: But doesn’t that get a bit dull? A little variety wouldn’t hurt.
Jiro: Variety means deliberation. Deliberation means wasted time. Green works. Like in shopping. I walk into UNIQLO, I scan for green, grab it, and I’m out before the agony of choosing can set in.
Hiromi: Taking minimalism to the next level. Impressive… and alarming.
Jiro: It's just applied simplicity. Less decision fatigue, more mental energy for things that actually matter.
Hiromi: I feel like you’d wear green even if the only options were neon lime or mossy swamp. 
Jiro: Within reason! I’m not going for any radioactive look.
Hiromi: Imagine if UNIQLO stopped selling green. Wouldn’t that be an existential crisis? 
Jiro: I’d just find a new store—or stockpile enough green to last a lifetime.
Hiromi: If we ever go to a formal event, please don’t tell me you’ll just wear a green suit. 
Jiro: I have limits. I can make exceptions for tuxedos.
