On women, no real preference, but I have to say, fake nails just seem so lame to me. I don’t like bright flashy colours on nails, either. Long nails with dark colours can be cool though. Fingernails that are only long because they’re not looked after are just nasty.
A man with long nails is a bit odd, and a turnoff for me. But that’s when they grow them for reasons other than looks. Like holding joints or just not taking care of them. Guys who grow fingernails for looks like some women might is kinda cute.
I met this Goth once though, who grew out his fingernails on one hand like an inch each, and that was what went passed the fingertips. That was interesting, I’ve never actually seen real human fingernails that long before.
That lady in @ragingloli‘s pic though…what at @Blueroses said. How does she get anything done? I remember that Indian guy in the guineas world records, who had uber long nails, and his wife basically spent most of her time just taking care of his hand. After a while, she was like, dude, come on already.
