lass, I think there is a distinction between attention-seeking, and raising awareness - isn't there?
This woman started a widespread conversation. Many people -sadly, less perceptive than you - noticed that men at these events tend to wear similar outfits. Now, I do understand that you have stared at these men and their suits in great detail, so you feel it's really unfair that we noticed they all looked about the same. But, sorry ... they do all look the same.
Women at awards, OTOH, are required to look very different.
This is a bit, you know, unequal in terms of gender. Right? So, the answer might be to try to raise awareness. Obviously, a feminist raising awareness might anticipate a negative reaction. Misogynists often come out with those. But, unless a person is a misogynist or rather witless, they'll probably support her, won't they? So what is the issue?
