Yes Apple Cider Vinegar will work to get rid of feminine "Vaginal Odor" I've used Apple Cider Vinegar myself to get rid of the odor of my Vagina it worked great.
You can either drink it or soak in a bath with Apple Cider Vinegar.
What I did though was make an Apple Cider Vinegar bath by mixing two cups of Apple Cider Vinegar with your bath water and then soak in the Apple Cider Vinegar bath for 30 minutes or longer if you want too.
But do make sure you stay in the bathtub for at least 30 minutes for the Apple Cider Vinegar bath to work to get rid of your Vaginal Odor.
If you want to you can also drink a glass of Apple Cider Vinegar by diluting two tablespoons of Apple Cider Vinegar in a glass of water and drink that.
Soaking in a baking soda bath can also get rid of your Vaginal Odor if you don't have any Apple Cider Vinegar.
Just add a half cup of baking soda to your warm bath water and soak in the bathtub for up to 30 minutes.
Eating Yogurt on a daily basis can also help to fend off Vaginal odor since the good bacteria in the Yogurt can fend off the Candida infection that is known to cause Vaginal Odor.
