It's very dated;
Carly is one of those names that surprises me when I see it. Like, people are still naming their kids this? Oh, ok. It's definitely on its way "out", it's had its day, so it seems a bit...anticlimactic.
The sound itself is kind of appealing, there's a warmth to it similar to
Amber. But still, I'm not fond of it.
Carlie is kind of ok I guess? I don't like Carli or Carlee at all.
Carly seems the most flat and lifeless.
