There are some that will judge by looks just like in rl for some it can show a status of wealth.
That is not to say some choose on purpose to wear something to express, as an example a dolphin with mechanical legs and a headset in space yes!
Did i like it sure the look was much more interesting than a typical smooth looking mesh. Some forget we are also here to escape rl than to create a virtual rl.
I am still donning the system avatar :D
