Right now, I'd have to say
Betty. It has a kind of retro charm and sweetness to it that I find endearing.
Ellie is my second favorite because it's such a soft and pretty name, though it's rather trendy.
Eliza is also cool in a Victorian kind of way, though I don't like it as much as I used to.
Bette's okay, but I really don't like
Beth. It's one of my least favorite names.
