The latest fashion trend to blow up on Instagram is people donning detailed images of female genitalia on their hands.

Dubbed the 'vagina nails', women are painting the images on the tips of their fingers and the reason behind it isn't exactly clear.

Not all the images are vaginas but some women are drawing other genitalia including breasts and penises.
