Not in royal blue, either, but I'm allowed to wear white, so I do. Not as see-thru as some other brands, although I avoid garish boxers. I was wearing the Landau zip-front tops, but switched to Cherokee. Different brands have different royals, but if you're pairing them with white, it doesn't matter.
I really liked Crest, but can't get them anymore. Their pants didn't have belt loops, though. Didn't find any until the Landau 7-pockets, although I've heard some Dickies have belt loops. It's an issue for me since my six-pack became a keg (okay...it was always a keg) and I had to wear suspenders, especially after my pockets get full. The zip-fronts make going to the bathroom a lot easier when you're wearing suspenders. And I like the way they look--been complimented a few times on my "manly" uniform.
