Whatever I can find at Macy's or similar works for me, too. We wear the standard U navy, and finding a match or close enough isn't hard. I do keep one pair of "official" M&H pants in the closet, but they don't match my jacket any closer than the department store pants. The M&H pants are $65, while the ones from the department store are usually around $40. Better yet, the bigger savings come every week: The department store pants go in my washer rather than needing a trip to the cleaners..
