We have another wedding coming up in August..the second son to marry this year. Our son is insisting his Dad rent a tux...a cost we really cannot afford. Dad has a nice soft black suit....think that will be ok? What is the traditional wear for the FOG? You'd think that with this being the fifth child to marry, we'd have this all figured out, but this is the first son to marry in a traditional ceremony in a church building. Any feedback would be appreciated....
