Do you think that I could wear this outfit out with my friends out on girls night out ?

The outfit in itself is fine. The bigger question has more to do with you. If your friends accept your hobby and know who you are, I don't see any problems. However, if you see it as more than a hobby, and have a real pion for it, I think differently. If it's a costume party, most will think it's just a one time thing and may offend you with their conversation. If you are prepared to be possibly offended by people you don't know, then go for it and have fun with the people you care about. If you are at all sensitive about your crossdressing, then keep it between friends. Good luck.
