I ride without chamois, they just don't feel right. (now that I have a saddle that really fits me -finally!- the chamois has become irrelevant)

I really love the UnderArmour ultra compression shorts. They come in a few lengths, but 2 lengths are really good on the bike: 4 inch and 7 inch inseams. http://www.underarmour.com/shop/us/e...rt/1001226-001

The 4 inch inseam work very well as undies for everyday wear, and the longer ones are toasty warm in the winter.

Handwash them in Head and Shoulders dandruff shampoo every few weeks if they get stinky.
