We are having a simple wedding in a church on March 9, 2014. I have a tea length ivory dress. We are having a marton of honor, a best man, and my son is walking me down the aisle. The guys are wearing a shade of purple shirt and black pants with a tie. The problem is: my groom needs a shirt that has 18 1/2 neck and a 37 inch sleeve. They are hard to find. Would it be acceptable for the men to wear short sleeves?
