Candy in itself sounds far too cutesy, and the name has a bad reputation as trash, so misspelling it doesn't exactly help your daughter become successful, as people tend to make judgments about others based on all sorts of things, like their background. If a person has this name, spelled in this way, people might think the parents were bad spellers and not very bright. People might also think the girl or woman herself is kind of dumb.
I have this name "Kandi". It has caused me seriously bad trauma in my life. I was exposed to a lot of unintelligent people growing up. Men can be very sexually creative, unfortunately. Not only was I questioned whether or not I was a stripper, my whole life, but girls were very jealous and obnoxious when they heard my name. When I was 21 I met a man. We were introduced and when hearing my name he felt compelled to lick my arm (to see what I tasted like). I then changed my name in my life, not legally. However, this name can be pretty given the right circumstances, I think?
