Don't worry about it. I can tell you that my husband went through the whold prosses to become a catholic and none of the adults where wearing all white. If you aren't under about 25lbs you aren't going to find a white outfit for a boy. We just had our daughter baptised in a catholic church and we used the flower girl dress from my cousins wedding so I didn't even buy anything for her to wear. The pastor kept telling me to relax and enjoy it but I'm so uptight that I just had to chase her around the whole time because I thought she was being dissrespectful. Good luck and just relax. Black, gray, or purple pants isn't goimg to make or break the day.
