Ideally I would just buy 5 or 10 pieces of what fits me. The problem is that I am not Steve Jobs and everybody will think that I never change clothes.

So I buy a few of varying colors but this is the extra effort I would like to avoid.

I tried this with my first son when he was a few days old. One pajama (or whatever it is called) was great so I went back to the shop and bought 10 of them. Then went back to the shop to return them after my wife explained to me a few facts of life.
