It looks more refined to me.
I know that
Katherine and
Catherine are both *proper* spellings, but because of this trend of spelling C names with a K (
Khloe, Karter etc), it makes me view
Katherine less favorably then I do
Catherine. The whole 'K instead of C' trend has ruined
Katherine slightly, as my mind seems to paint with the same brush, even though I
know it's a proper spelling. Silly I know but there we are.
