I'm not a fan of
Philip (really starting to love
Filip) but
Philippa is nice (though I like
Filippa more some days).
Philip just sounds very stuffy 16th century king. I like
Pippa (though I'm sure in
America right now everyone would be like "
Pippa Middleton?!"). I don't know how I like
Pippa on a professional adult though and
Philippa sounds so stuffy to actually be used on a day-to-day basis so I doubt I'd ever use either name unless I had other incentives.
