You also don't see men watching "The Red Carpet" at pre-award shows. Neither do they comment on suits that men wear. Women are a lot more competitive with one another about appearance. It's not uncommon to hear one woman say to another; "Did you see what (she) had on?" or "She is too fat to be wearing that?"
Traditionally women have focused on beauty in order to attract men. Historically men were the financial providers and women were in competition to get a man who had a great career. Today many women have better job opportunities and earn more money than women of previous generations.
However men have not changed with respect to approaching women whom they find attractive. The male mindset has always been: "If I'm successful enough I can have (any) woman I want." We can see this still in action today. Hugh Hefner founder of Playboy Magazine at age 86, thinning hair, wearing false teeth got married to a 26 year old beautiful former Playboy Centerfold. Can you imagine this happening in reverse? Not many 26 year old handsome guys would rush to marry an 86 year old woman no matter how rich she was!
It's unlikely that men are going to change with regard to wanting whatever they consider to be a beautiful woman as a mate. If there is going to be a change it will have to come from women. I see overweight women slam thin women as well. The slogan "Real Women Have Curves" is a knock against women who don't have curves or who were born naturally thin. Whether a woman is overweight or thin/fit she is a "real woman"!
Self-esteem is something you give yourself! It's a slippery slope once you begin (comparing yourself) to other people. Again this seems to be something women (enjoy) doing when looking at other women. As a man I could care less what another man looks like. We're NOT "competing" for attention.
Last but not least as long as women buy all the magazines, products, and get the surgeries there will be businesses fulfilling their "needs". Until then People Magazine will continue to write articles titled "Who wore it best?" when comparing women that wore similar dresses. If it sells they'll keep putting it out there.
