It is a fine name. I don't love it but I don't really dislike it either (no help here) I personally think that it is a little heavy for a girl, and that it doesn't age well. I would use Charlotte and nn Carly
I like it. Besides the kids show iCarly it isn't a name you hear very often. I think a short one syllable mn would sounds best, especially if you have a long(er) last name but if you have a short last name then a longer mn would sounds better.
Carly Anne Carly Jane Carly Dawn Carly Rae Carly Paige
Carly Elizabeth Carly Isabelle/a Carly Joanna (Jo)
Carly is not my style but nothing wrong with it. Just doesn’t sound pretty to me. I agree a one or three syllable middle name would go best depending on your last name. Adding suggestions
