Do they make tuxedos for babies?

My sister and I were talking about what to dress Ethan in for her wedding in December and I'm struggling a little bit. Her main colors are frappuccino, champagne and ivory. Of course the guys are wearing black tuxes with ivory or frappuccino vests. I'm not sure if I should get some sort of black suit or more of a khaki suit. I will go shopping with my mom tomorrow to South Park mall in Charlotte so I may find something there, although it may not be the price that I want it to be! I'm also going to a consignment sale in Rock Hill this Friday so maybe I'll get lucky and find something there. All of us moms know that we don't want to spend a fortune on an outfit that will only be worn once! I want to find something cute that he could wear all winter if possible. If any of you have ideas on where to shop for something like that, bring it on!
