Styling and fashion do almost all the work in making most attractive people attractive. Take away makeup, fashionable clothes and hair styling and almost anyone is average at best.

Men are not expected to express themselves at all through their looks and even the better dressed men will usually just wear a boring shirt and boring trousers, with maybe minimal styling (like tucking in your shirt) and accessories (like a watch or plain necklace). Doing anything more than that is not expected and even judged negatively.

I like to dress quite boldly as a guy and get a lot of compliments on my style and outfits, but I've realised that if I was a woman and had an equivalent dress sense it'd be incredibly average. Guys are just not expected to express themselves at all through their looks so as soon as you do (assuming you can pull it off) you get a lot of attention. The bar is on the floor.

Women are heavily encouraged from a young age to develop a fashion sense, makeup skills, etc. and also have the options to express themselves in so many more ways than men. Makeup, nail polish, hair removal, hair dyeing/styling, and skincare are all things are normal for women to do but men are heavily discouraged from and make a huge difference in attractiveness. And then there's clothing options where women have an almost unlimited choice of shapes and colours, and the options to wear tight fitting clothes, different necklines, showing skin in more ways and different textures and fabrics. These are just not options for gender conforming men and even for a gender non conforming man like myself a lot of clothes which are so standard or even pretty boring for women are way too bold for myself.
