I know a lot of westerners ...male and female ....who wear these things. Now most of them are Muslim. They also happen to all be different races...but born and bred in the US, UK and USA, and I know quite a few of them wear it back at home too, whereas some of my Qatari friends and former co-workers don't wear National dress abroad. Just my experiance...that is all.

A funny note on national dress styles in general...in one of my arabic courses my fellow students and I were all discussing each others national dress (and where we found the best deals on abayas...) and I was asked about how the US doesn't really seem to have one as compared to other countries...the next class I did happen to come in levis and a nice pair of custom made cowboy boots...the boots were a hit.

So if you see someone in abyab and hijab...with cowboy boots ( I collect them actually) ...proabably me.
