Subtle shirts?

yostinso thought this was worth mentioning said

What about small prints or more subtle designs? Although I still have a half dozen shirts from Threadless I got back in the oughties my wardrobe has gotten a little more restrained and I would be super excited about shirts with either small-area designs – pocket sized or just full-width but vertically short.

Oh man, now I kinda want to see pocket tees with just awesome designs on the pocket.
