Where you're wrong is that you suppose I'm talking about "moral" matters when I'm exclusively talk about "beautiful" vs "ugly", "cool" vs "weird".
Do men clothes can be worn by women? Absolutly. That's unfair but men clothes on women, clothings can match but women clothes on men... the truth is that the reply, most of time, is an absolute no. Men don't "fill" women clothings.
Even considering one gender, all clothings don't match all people. I would never wear "gothic" or "bikers", I watch out if it is "sportwears" because not all cuts will match. Because it doesn't fit me. I've realized long ago that not everyone can wear everything. Some people, but they are rare, can look cool whatever they wear but most people don't have this chance.
I don't care about moral. It's not my angle.
