I am throwing a baby shower for a friend of mine, who is a first time mom. She is really worried that because she is having a girl everyone will just buy her clothes, when they really need gear because they've gotten lots on hand me down clothes and are on a budget.

Is there a polite way to ask on the invitation that people buy gear rather than clothes? I was thinking something like "Help these first time parents outfit their nursery, they are registered at Amazon."

Or should she just be happy that people want to buy her gifts and return/exchange them if she ends up getting too many clothes?
