I play a male Roegadyn right now, but when I was a female Au Ra, I used the Thavnairian set simply because I liked it. I didn't run into anyone that looked exactly like me despite me using a very common glamour choice. I was able to design my Au Ra to look more unique, I daresay more so than my male Roegadyn which is a far less played race. To put it simply, you need to try harder. If you go for that generic look, you will look generic, but if you take the time to think outside the box, you WILL be able to get something more unique.
