I think it was Glamour where I first saw this, and I felt so instantly conflicted that it could only mean one thing: another Hot or Not post!
So this nail trend involves starting with a base color, then mixing in varying degrees of white or black nail polish, to get an ombre look that fades from dark to light. When it comes to nail polish, I generally have the same outlook as I do towards my tacos: KISS (Keep It Simple, Stupid). Why let a good thing get out of hand (ha, ha)?
Then again, I can't deny that it's kind of pretty. Definitely classier than multi-colored nails and scary add-ons. But what do you think? Gimmicky? Smacking of tacky? I can't decide.
P.S. I'm actually pretty impressed/intrigued by the nails in the third picture (above). I'm sure that takes a lot more patience/nail painting skill than I have.
