I like
Oona. It's memorable and wacky and most people hate it, just my cup of tea. It is totally over the top, no denying, so you have to be comfortable with that. Don't even try to pretend that
Oona is a
Julia or
Chloe or
Emma. She's not and never will be. She's
Oona. You will get a lot of funny looks and stupid comments about it, so you must be
Oona's champion and defend her honour.
Those combos are great. I really like
Oona Frances and
Oona Vivienne.
