Leg Shaving and the Law of Moses

So, I was thinking the other day, my legs grow hair at an astonishing pace because God made them to. So that hair must have a purpose then musn't it? So then is it unwise for me to shave it off? Is it only vanity and conforming to the social norm? Yes, I find it gross to not shave, but that is largely due to the culture I've been raised in. I certainly wouldn't say it is sinful to shave because I don't know of anywhere that God specifically states that you should not. Perhaps if I were doing it with a rebellious heart it would be; that being after I had had a directive from God that I should not shave and did it anyway. What if my husband did not want me to shave but I did? That would be not submitting and so most likely indicative of a heart issue that was sinful so therefore shaving in that instance would be sinful. But I'm not in that scenario either, I'm just wondering. Because it has to be there for some reason and I don't want to be unwise. But maybe leg hair is a result of the fall and therefore no longer serving it's created purpose and therefore can and should be removed? I just don't know. "'tis a puzzlement!"
