It goes both ways, though. Wearing makeup and heels is not an obligation -- lots of women don't feel they "have to put that shit on" -- but if you want to gussy up a bit, you can. Men are stuck with a more limited range of looks. Tell you what, I'm a straight woman, but I seriously feel there are many more attractive women than men, and I think it's at least partly because they have more beautifying options.
Well, true, but I don't see it that way.
My wardrobe is as limited as I want it to be. I have shirts in tons of designs and colors, and dress slacks or jeans. I have about 10 pairs (probably more) of shoes, sneakers, boots. I have 3 different blazers, some hats.
Do I want my head shaved down to the scalp? Go clean shaven? Just a mustache or goatee? Beard line?
3 different leather jackets, 2 denim jackets.
4 differnet watches, various bracelets, necklaces, belts and buckles.....
Whatever mood strikes me, I can find an outfit and accessories.
Yes, women may have more options, but when I maximize the options I have, I don't feel limited in the least.
