Obama also has commented on his choice to have only one kind of suit. I have a few friends who do the same. Not saying that it makes you Obama or Steve but it isn't uncommon to optimize that part of life away once you have a suitable outfit that looks good.
That is funny actually because people made a big deal about it, so when you are the president and have people paying attention to what you wear that gives you another reason to just stick to one good choice.
My source was this article, maybe Obama doesn't always follow his own advice:
