It’s a little too childish - cute on a small girl, maybe, but pretty ridiculous on an adult. I know it isn’t so different to a nickname like
Libby: it just somehow sounds and feels younger and sillier.
I knew a set of siblings called
Harry,
Lulu, and Tiggy - I think everyone at our school felt they had pretty ridiculous names (Harry’s fine on its own, but lumped in with
Lulu and Tiggy takes on its own childish sound too)
