That would be me! I have a white pair of button-fly 501, and they look dang good on me too!
I have a collection of my favorite Levi Button-Fly; light blue, dark blue (indigo), acid wash, white, and black. One color that I didn't see is burgandy or red. I'm looing for a pair size 32x32, if you know where I can find a pair in that color let me know! Then I have a pair that's wore out in all the right spots.
