I like
Irena ok and vastly prefer your "Italian" pronunciation.
Irene I would most definitely pronounce "eye-REEN" though, and like even less. However I know an
Irene and it REALLY suits- she has a very "pinup" style (dark hair, clamshell bangs, red lips, defined brow) and pulls it off nicely.
Bianca is ok too. I've warmed to it more lately but still don't love it. It's always sounded like a "stuck up" name to me, like I've seen too many movies/shows with a mean rich girl named
Bianca.
Nadine is my favorite of the bunch for sure. Some days I like it more than others; today is an off day for me =/ but next week it could be a favorite. It's..... Comfy. I dunno, I keep getting an image of a soft, oversized, mustard yellow sweater... and chocolate chip cookies... and a pretty smile. Now, are you pronounce it "Nah-" or "Nay-"?
