Nun Beef

I just thought about a beef I have with nuns. Ok....they dedicate themselves to a life of humility, poverty, modesty, masturbation, etc.....so, why do they draw attention to themselves when they go out in their full costume? In my opinion true humilty would be going out in sweats, or jeans and a T-shirt...not in some get-up that screams "HEY LOOK AT ME!! I'M A NUN!!" It's not like they have to dress that way so that in case we sin while we're out in public we can approach them and confess.....the priests take care of that job, right? I just don't see the humility in that get-up. Now, this is a rhetorical question....just so ya don't think that I'm clueless when it comes to Catholicism. I'm very familiar with Catholicism....I've seen many different factions. I'm not wanting a lecture on this....it's just a beef I've always had with nuns.
