For the minimalist:
Two pair of bike shorts. If your shorts don't dry overnight you will get industrial strength blisters in places you never knew you could blister. I ended up bent over a MD's table having my butt debrided while ordering a second pair of shorts to be drop-shipped to our next stop. It was not a pretty sight...metaphysically either.
Two pair of bike socks, unless you wear sandals in which case 1 pair will do.
Layers for the top, one of each layer. Who cares if they get wet. If it rains, you can always wear a rain jacket with nothing underneath.
One set of off bike clothes including shorts, shirt, 2 undies, sandals. You can always used outter layers of cycling clothes off the bike in bad weather.
Believe it or not, the only difference for women is a dress with built in bra for off the bike and a few pairs of earrings and maybe a shawl for dress up occasions.
We have gone for three weeks with nothing else. I'd rather carry tools, a tire, a few spokes, a camera, kindle and FOOD.
