I can only wear one kind of pants, all cotton knit, so of course I have many colors of same pants. I feel kind of funny wearing the same pants to work all the time. The winters are hell as these pants are not thick or warm.
As a New Yorker, my favorite color for work is black, so that didn't bother me as I already had a bunch of black cotton knit pants for dressy casual that became work wear when i got TM.
Mine are different weights -- there are heavy weight cotton as well as light weight. Eddie Bauer,
