To Pocket or Not to Pocket?

Antonio, big fan.

I’m going to have some shirts custom made (Woo).
I guess the purpose behind the shirts are dual in nature:

1) to wear over chinos/slacks/pants to give the ensemble a formal look
2) to (potentially) wear with a suit.

My question pertains to pockets and your thoughts on them. Given the purposes´╗┐ i have for the shirt’s use, should i order them?
