dressing up is fun and depending on the scenario can add a lot of atmosphere and more reality which to me makes it even more enjoyable plus it can make people feel more sexy.
going out is fun with a 'reminder' too, fetish wear at events or even at 'vanilla' fancy dress partys ...you can get away with allsorts hehe or just going to the local shops in a simple breast/crotch harness, clamps,bells etc or certain types of underwear can make you feel very different and it sometimes makes me feel a bit vulnerable too which is a turn on.
the only thing i dont like although i guess in all honesty its a bit judgemental especially as i enjoy exhibitionism is when people go way ott with it simply just to prove a point and shout out hey look at me im different in regular public places.
