You HAD to wear a suit? Were you in the wedding party?
Gosh, if you weren't in the wedding party, and if I were a guy I would wear a short sleeve shirt.
I live in Redneckville but I own no, none, nada, short sleeve dress shirts. The wedding was formal and the Bride is my daughter's best friend since 7th grade. She is my co-daughter. My daughter was matron of honor and I would not have even entertained not wearing a suit and tie.
