Chelsey or Chelsie?

[name_m]Just[/name_m] want to know some of the opinions about these teo spellings. Which one do you prefer, why, and can you:
A. See it on a child only (sounds too cutsy to me)
B. See it on an adult only (not girly enough [name_f]IMO[/name_f])
C. See it on both a 2 year-old and an old lady (this name is absolutely perfect and gorgeous!)

For C it’s actually “this spelling”, not “this name”.

I can’t really see it on an old lady. I can see it on a child and an adult but when I hear the name, I just instantly think of a teenage girl.

Between those spellings I’d choose [name_f]Chelsey[/name_f] but out of all the possible spellings I prefer [name_u]Chelsea[/name_u]. The only [name_u]Chelsea[/name_u] I’ve known was spelt that way.

I couldn’t see it on anyone 30+. I automatically see it on a teenager, but more the [name_u]Chelsea[/name_u] spelling.
