Which gender has to spend the most money to retain a respectable place in this society?
Let’s ignore gender rights issues like sexual harrassment and false accusations for this thread.
Well lets see. Women spend more on hygiene products, but earn less money. But they get free drinks in bars.
Women live longer so their life long health expenses are higher (about 80k over the course of a lifetime I believe).
All in all, its more expensive to be a woman. You earn less and your health costs are higher.
Women’s clothing costs more and doesn’t last as long. And the pants don’t have pockets.
(Kind of a shame, though, that men can’t carry purses. It’d be nice to haul around more of my useful stuff. I make do with cargo pants.)
Women’s clothes generally cost more and change styles much more rapidly than men’s clothes do.
Shoes aren’t cheap.
It’s more expensive for a man who is married to a woman. 
Duckster FTW. 
Let’s not forget the courtship phase!
Men have to spend a great deal of money on women. That is not necessarily true in the reverse.
Basically I was coming in to say more expensive to be a man, assuming he wants to have sex with a woman.
I spend more on clothes, but my husband spends more on dry cleaning. I work in a more casual office, though.
I had over 30 years of prescription birth control to buy, and also the associated products for dealing with menstruation. I’m not sure I can think of any comparable costs for the average man.
Our “courtship costs” were about even, since we were students at the time.
I always stipulate that my dates have to be cheap. So from my experience, it costs very little for the upkeep of a woman.
Medical care for women is more expensive.
Women’s haircuts and dry cleaning cost oodles more too.
My wife works from home, so her clothing costs are even less than my not very big ones.
Dry cleaners? Only for weddings and funerals.
I suspect her contraception costs over time were more than my one time and final cost.
I’m allergic to perfume, so that hasn’t been a cost for us. (Best allergy ever!)
If you don’t count pregnancy costs, the biggest cost for her over me is pocketbooks and bags. She gets good Coach ones, I just buy any wallet I can find which meets my requirements.
My ex claimed that the price of haircuts were unfair (because women are charged more). But I paid more per annum, because I got my hair cut a lot more often.
Kind of a loaded question and depends on your standards/morals.
I think Daniel Tosh summed it up something like “being an ugly girl is kinda like being a guy - you’re going to have to work for a living.”
There are plenty of guys who go through all kind of effort to attract women and vice versa.
If you are an attractive woman - you can pretty much coast through life financially
It is not socially acceptable for a guy to do the same thing.
If you take mating rituals out of the mix - then I think in general being a woman is more expensive, but you can also sell your body for much better rates than a man can (legally here - eggs vs sperm).
However - if you include mating rituals.
I’m pretty sure once you put into what guys spend to try and make themselves more attractive to the opposite sex - they spend more. There are plenty of women who spend plenty on fashion/makeup and the like, but much of that really isn’t needed to land a man.
If you look at the poorer quartile of men and women - I bet women spend more - and if you look at the upper quartile - I bet men spend more.
I’m talking single here.
Women are more expensive, but typically those expenses are paid for by men. Well, maybe “traditionally” is a more appropriate word than “typically”.
From least expensive to most expensive (assuming heterosexuality):
Single man
Coupled woman
Single woman
Coupled man
I’d pay 80K to enjoy seven more years of life 
Seriously though, one expense that women pay way more then men is funeral costs… In our society, it raises far less eyebrows for a woman to marry someone older than her than younger than her. Thus, wives end up outliving their husbands and have to foot the many thousands of dollars for the funeral.
How about razors and related shaving paraphernalia?
