Why is it if girls like to have and are freaks they're considered tramps?

I love , and experiencing new things and have a fun life. I am faithful when I have a partner. When I'm not tied down I like to have , and since I don't have a boyfriend or anything I can do what I want. I don't over abuse this though. I do wear low cut shirts and look y, but I see it as being proud of my body and flaunting it. I don't see why people don't like it. It's not like i walk around in nothing but my revealing clothes are tasteful not slutty. I also don't wear them all the time, just if I'm going out. I also have large so it's hard to hide them so even if I don't mean to look provocative I still do. Why are people so judgmental and call girls like me tramps?
