For most occasions there is a standard way for a man to dress and no expectation that he wears something new each time- for example- wedding=suit, business meeting= suit,interview=suit, black tie event=dinner suit. For women there are always numerous subtle ways that she could get the dress code 'wrong'
Oh my goodness, yes. 
And what makes it even more difficult is that it is becoming nigh on impossible to purchase reasonable formal "occasion" clothing if you are female.
DH and I have just taken on a formal representative role in our area. For DH, this is a question of one black lounge suit and coat, and possibly one evening suit, with one pair of oxfords and a one decent white shirt.
For me, it has meant four day dresses with appropriate jackets, bags, and shoes and two hats so far. To do the whole thing cheaply, I'm scrutinising the stock at New Look and online sales sections, borrowing hats from my mother (who is in her 70s), and even after burrowing through online shopping site after site, I only found one yes, one -- appropriate cream jacket at a reasonable price to make the whole thing work.
Then it's the hair and the nails and the tights and the appropriate makeup (and the appropriate bra) ...the amount of effort involved is bonkers.
My mind just keeps flickering back to Germaine Greer's comment where she says that this is all unpaid work. The shaving of legs = work. The grooming of nails and hair = work.
And to be honest, I'm getting cross about it all. And that crossness is opening my eyes to other unreasonable expectations.
Like fucking bikinis and swimsuits. If I want to take my toddler swimming, I have to ensure that I plan to shave my bikini line the evening before. I can't be spontaneous about it. I have to plan, plan, plan for everything, and it pisses me off no end. So I did a cursory look for a swim set that had shorts, and the only thing on figleaves with shorts was bloody £96.
And that is the problem, to my mind: unreasonable expectations.
To put a figure on it, I totted up how much time it has taken me in my life thus far to shave my arm pits. Presuming two minutes three times a week for 30 years, I worked out I have spent 156 hours of my life yes, nearly an entire week just shaving under my arms.
I dread to think what the figure would be if I included shaving my legs as well.
