A really pretty name, in the same vein as Zoe. Yes, there was a surge of popularity in the 90s (and 80s?) but so what? It's still a classic Greek name, found in poetry and other literature, and not faddy in the same way as Kimberley, Chardonnay etc. It's a bit short-sighted to equate it with names like that.
(So long as it's not spelt Khloe!)
