Feminine form of Charles?

Lindsay • Gwendolyn Eloise born 2.10.19 👶🏻🎀

So I'm wanting to name my baby Charles, but turns out it's a girl! I'm dead set on the name, but want to make it more feminine. I know the BEST way to feminize a name is to replace letters with y's... so what do you guys think of this?

Yyyyyyy - pronounced Charles!

Middle name will be Rose.

Yyyyyyy Rose
