Odor and such

Cat
I'm 18. My BF and I are choosing to go the abstinence route. I'm a virgin have an actual goal to stay that way until marriage. I have a question about vagina odor, though. I wash (that area, obviously.) every other day (I take a shower every day, but I read that you can get rid of all the good bacteria and really, you're not supposed to wash at all). When I wear things like leggings or high waisted skinny jeans, or even tighter underwear, though, I get an odor down there. And I want to know of a way to stop it. It's not a necessarily -bad- odor. Like, it's not something I think I should be worried about. Just kind of embarrassing and I'd like to know how to have the best hygiene and cleanliness as possible. 
Thanks.
