Although that is a legitimate point, let me give a counterpoint...Most people don't know this but high heels were actually worn by men before they were worn by women, because high heels give a feeling of elevation and power. Sounds narcissistic I know, but that's why high heels are so sexy on a woman. They elongate the legs, making them longer and slimmer. Speak to any woman who likes heels and she will tell you that they are empowering and help her to feel confident. For some women that confidence is innate and for some it's fake and goes away the second she takes those heels off.
Ever heard of Platform shoes? They look infinitely more comfortable, infinitely better looking for young people, and are freaking stylish.
Meanwhile, High-Heels look awkward, Hideous on young people, only worn by older Women, and once the heel breaks off (Which it will) you're left with something that looks like it should be on the feet of roman Gladiators.
As for the chance of doing something to your ankle? About the same.

Anyways, I don't really understand anything that can't reasonably be assumed to be suitable for both genders as a norm. Save for Bra for Women (Since that's important for at least some women, though not necessarily all.).
So basically: Skirts, Dresses, High-Heels, Earrings, Baggy Shorts, Hairbands, Scrunchies, Pantyhose, Corsets, Girdles, Frills, Kilts, Beards, mostashes, Perfectly Shaved or Trimmed anything, Great Long Hair, Extremely Short Hair, Purses, Clothing without Pockets, Backless clothing, Clothing that exposes Midriff, Gowns, The majority of hats, anything that is only held up by tiny strings, stuff that is only held up by how tight it is, Ribbons in hair, brooches, Braids, Ponytails, Pigtails, See through anything, Necklaces, Tiaras, Rings, Bracelets, Belly-warmers, Plunging Necklines, G-Strings and Thongs, Most Robes, Fishnet anything, anything tied or woven into your hair, Loincloths, Anything with a complex color pattern, Flowers, Jeans...
Yes... I just said Jeans... They don't suit any gender since they are rigid as hell and hard to move in... Now Where was I?
...Sandles, Flipflops, Lipstick, Blush, False Eyelashes, eyebrow Trimming, Fake Nails, Nail Paint, Nail Polish, Mascara, Eye shadow, Bra-Stuffing, Water-Bras, Breast Implants, Breast Reductions, Nose jobs, Collagen Implants anywhere, Speedos, Bikinis, the so called "One-Piece" Swimwear, a toupee, Piercings anywhere, Shoes without a tongue, Cod-Pieces, Budgie Smugglers, The act of Stuffing your Underwear, Crotch Pumps, Glitter, Anything encrusted with gems or Pearls, Ribons, Bows, Streamers, Aprons, Veils, Head-dresses...
...
I think I'm Running low on things I can list off the top of my head... But Needless to say, If I can tell your gender just by looking through your wardrobe, I don't understand your fashion.
(Androgyny for the Win!)
