Kim Kardashian Almost Goes Full Frontal in Nude Photo

Kim Kardashian is following in the footsteps of Amber Rose with an almost completely exposed shot of her crotch ... but there's one major difference.

Kim posted a VERY risque photo Tuesday of her bottom half, but not the side we're so used to seeing ... this time we got a close-up view of her midsection from the front, and the starting route down to her vagina.

She was advertising her new fragrance line, obviously.

She also shared a topless photo of herself as part of the set -- but, let's be honest ... we've seen all that before.

Kim's slick front shot, however, is quite a sight to behold ... and quite different from Amber Rose's crotch shot last year ... which was more hippie than lippy.
