Kim Kardashian Lets Nip Slip in Nude Pic for Fragrance Line

Kim Kardashian's baring it all for her new fragrance line ... but it looks like she missed a spot this time while strategically covering her lady bits.

Kim posted another very risque pic Tuesday to promote her perfume -- KKW BODY -- and got creative with a new close-up angle from the front. Only issue is ... a little nip can be seen, which might not fly with Instagram's no-nudity policy.

So, enjoy it while you can.

As you may recall ... these nude shots have been part of the marketing campaign for her fragrance from the jump -- the last one featured even more vagina.
