I conceed that it is not a man/woman thing but a Mr. B thing. Suit "equity" sounds most like what he was trying to explain but he got off on this rant about how spending so much for clothing for one day is symbolic of everything that is wrong with everything. While I do kind of agree with that I don't see how spending more money on something that will be worn for one day improves the "everything".
It may not have anything at all to do with the suit itself. In these uncertain financial times, even the richest people amongst us are having to watch their more extravagant spending habits.
There is a lot of uncertainty about the immediate future for the economy. People who own businesses are nervous about the survival of the business and the workers they employ. People who have jobs are nervous about losing them. Those that don't have jobs are nervous about how to keep finding money to pay bills and put food on the table.
Maybe Mr. B needs an opportunity to just vent his own nervousness so you can reassure him that you're still working with him rather than against him.
His whole point is probably about the need to make an appearance of prosperity such an expensive formality in these conditions and has nothing to do with the actual transaction of renting or buying the suit.
