At risk of sounding a bit misogynistic - which I absolutely refute - I've got a bit more to say about normal or expected gender stereotypes, which I mentioned earlier.
I think I might have also already mentioned some of the following a couple of months ago.
Firstly I must declare that I have not seen the show that curiousk referred to when he started this thread.
The lady shaves her face. I know it isn't in the same league, but isn't this just a massive magnification of what many post-menopausal or elderly women do now, dealing with errant hairs growing out of their chins? What about shaving legs and underarms, which is now considered de rigueur for all western women? There are probably more shaving and grooming products available for women than men when dealing with facial and body hair! A woman buying shaving products whether for herself or her man would also be considered normal, but a man buying a bra? Yes, it should be normal for those who need to, but I suspect would be viewed with suspicion most of the time unless the client has built a good relationship with the salesperson or has gone to a specialty store, yet there are still the reactions from other customers to deal with.
Jeans were invented for men working in mines around 150 years ago. Women didn't commonly wear pants until well into last century and I was surprised to just learn that Levi's didn't release jeans designed for women until 1934. Now it is normal for women to shop for and wear jeans especially designed for them if they want to - and they look fantastic - but it is not normal for a man to buy and wear a bra if he needs to, let alone if he wants to.
Regarding underwear, up until maybe the 1970's it was y-fronts for men, full cut panties or girdles for women. Thankfully there is much more choice available now for both genders, and women now commonly buy and wear a style known as boyleg briefs. But is it common for men to buy 'girl leg' briefs instore and get away with it? No!
Sorry, but the more I think about it, the less sympathy I have for Krystal.
I guess the question is, how can it be made fashionable for men to wear bras?
