I'm turning into a slut for wearing a crop top?

So the other day i wore a crop top, and now my friend is telling me that i'm a slut? I wore it with a pair of black leggings and you they were up so that you couldn't see my stomach unless i was stretching or something. I don't see how that is slutty at all especially since it's summer and i'm gonna wanna wear looser clothing and things like crop tops for the warmer weather. Things like this have happened before, i wear a pairs of shorts and i'm a skank. But I can walk to the beach with shorts and a bikini top and nobody will say a thing, it's all fine. Do you think it is slutty?
