Where do you get a Newborn Basketball Jersey?

I am newly pregnant and want to find a newborn basketball jersey to put "daddy's biggest fan" on the front. My husband plays basketball, so it has to be red with black letters to make it look like their jerseys.Where do you get a Newborn Basketball Jersey?
You probably could get the jersey from a department store and try your local mall for an airbursh or embordery store. They should do it for you.
