Alice or Annabella - I love both. I slightly favour Annabella as its more unique and sounds more refined, plus it has more nickname options.
Belle or Beatrice - Beauty and the Beast is one of my favourite movies, I have always been impartial to Belle. Beatrice is also nice but Belle is just cuter.
Cathy or Cate - Both seem like nicknames to me, but I prefer Cate as it sounds more youthful.
Darcy or Dorothy - Dorothy is just too old fashioned for me. Not a huge fan of Darcy either but I would rather be named Darcy than Dorothy.
Ella or Eleanor - Eleanor sounds more respectable. Ella is common and personally I don't think it would age that well. Eleanor is timeless.
Fiona or Felicity - Don't love either but Felicity is nicer.
Gretel or Grace - Gretel sounds too storybook. Grace is a lovely classic.
Hazel or Heidi - I have never liked Heidi, but Hazel is really pretty. A bit old fashioned but it could still work.
Ida or Iris - Iris is very pretty, Ida doesn't have the same softness to it.
Jade or Jane - Jade seems really cheap and its fairly common. Jane is quite simple, but its nicer than Jade.
Kara or Kasey - I consider Kasey to be a very masculine name, Kara is prettier.
Laura or Lauren - Laura is more unique! Lauren has become very common and boring.
Mali or Mia - Both names are very cute but Mia wins for me. Mali sounds and looks incomplete.
Nadia or Nelly - Nelly is cute, but I think Nadia would age better.
Oriana or Ophelia - Not really a fan of either but Oriana is prettier. Ophelia is very old.
Pearl or Penelope - Penelope is adorable! Good mix of cute and vintage.
Quin or Quintana - Quintana looks made up. Quin is better.
Rose or Rosa - I like just Rose, its a beautiful name.
Sarah or Scarlet - Sarah has become so common I find it really generic. Don't love Scarlet but its better than Sarah.
Tia or Tilly - They both seem more like nicknames to me, but Tia sounds more like an actual name in itself.
Ura or Una - Una sounds prettier.
Vada or Vienna - Vienna is nice. Don't love it but its better than Vada.
Wendy or Willow - Willow is kind of trendy at the moment but I think it sounds pretty and I like it more than Wendy.
Xaria or Xenia - I really like Xenia. Elegant but fun.
Yasmin or Yessa - Recently I have really begun to like Yasmin. Cute and less common than Jasmine.
Zara or Zarha - Zara! No need to complicate it with unnecessary letters.
