From a Uni Watch interview of NY Times' Yankees beat writer Tyler Kepner:

UW: Who is the most uniform-cognizant player you’ve ever encountered?

TK: Great question. Let me think. Gary Sheffield would drive the clubhouse people nuts. He had, I think, 32 pairs of shoes. And then he wanted gray shoes on the road, so he had 32 pairs of those too. He was always getting alterations to his jersey, and they were so subtle, you couldn’t even notice them. He’d want the sleeve brought up a little, or let out a little…

UW: Take a quarter-inch off the sleeve length, that sort of thing?

TK: Yeah. There’s this guy from Riddell or one of those companies — he’s always around the clubhouse, wonderful man. And if a guy gets traded to the team or needs changes or whatever, he fixes them up. And Sheff would give him all this work to do, and it would all get turned around in a day. Sheff, he was the most particular in terms of needing everything just so.
