I wore a lime-green T-shirt to lunch with Atsushi yesterday. We went to a putatively Moroccan restaurant, which turned out to be a French bistro-ish place (including the ham that came with the asparagus salad) in just about every respect except the figurines of camels and the baskets everywhere. Anyway, the color comes into the story because we both got pea soup--chilled fresh pea soup that looked like bright-green vichyssoise. When it arrived, Atsushi looked from my plate to my shirt to the (green) cushions and said, "You've certainly dressed for the place." Then the waitress came to do something with the cutlery and started giggling. "Same color," she said in English, looking at my place setting and me.
Unlike Janis, I can't wear most V-necks. I'm not worried about bra straps, obviously; it's just that when you have as much chest hair as I do, a deep V looks sleazy (in gay terms) or just plain wrong.

It's easy to look like duck.
