I think we are missing the point here. When even financially strapped families (who may have just spent $20,000 for a year in seminary) feel compelled to spend $4,000-10,000 on the chosson kallah watch, ring, machzorim, etc. and several times that on the actual wedding then a $400-$500 suit is just a data point and is in consonance with all of the other expenditures. There is no sense in hyper focusing on the suit when it is just part of the general problem of living a luxurious lifestyle beyond one's means.
