I've noticed a recent trend. Colored pockets! Yes, they are everywhere! On polo shirts, t-shirts - you name it!
Some brands have done a great job while others... Well, they've exaggerated. You want to look for simple shirts and matching colors.
Lacoste has launched its new spring/summer collection where you'll find the colored pockets.
Grey polo shirt with yellow pocket... Nice move, Lacoste.
I would actually take a look at the entire look book - it's very classy: http://www.lacoste.com/#/lookbook-men
