Elegant girls name with a short nickname?

[RavenclawWriter]

I hope this is ok to ask here. This is for a novel I'm writing. I'm looking for a name for my character.

She is a lesbian who is artistic and quite punky. She comes from an upper middle class white background (goes to boarding school) and will have been given an elegant girly name, possibly something from a literary or artistic influence. But it needs to have a short, possibly unisex nickname that she will use with her friends. Born in about 2002 and is British.

Any suggestions?

I used to go to boarding school with a Harriet (Harri) and a Thomasin (Tom).

Laurie would work as a nickname for Florence.

Regina / Reggie

Shania - popular due to shania Twain (not sure about nickname - Shan?)

Sorry but I am properly guffawing at the idea of an upper middle class public school girl being called Shania and Shan for short.

I was going to say Imogen or Clementine with Imo or Clem for short, but I think Jemima/Jem is a great suggestion.

Beatrice. Beattie Tricki
Mikaylah Mikki
Vivienne Vivi
Edwina Eddie Winnie
Francina Frankie
Wilhelmina Will Wills
Philippa Philly Pippi

Josephine - Jo
Juliet - Jules/Joolz

Of all the suggestions here, I like Artemis - Art the best.

Allegra is a bit of a class connected stereotype, though, but if that's what you're after it works well enough. Personally I'd go for something more neutral like Elizabeth or Catherine already mentioned.

Beatrice - Bee, Trix
Katherine - Kat, K,
Alexandra- Alex
Miriam- Miz
Cordelia- Lia

Antigone Tiggy Tiggs
Eugenie Genie
Henrietta Henri Etta Etti
Patrice Reece
Martha Matti

Clementina Lemmie
Azalea Zalli
Regina Reggi Ginni
Janine Ninni Ni-Ni.

Constance, Con

I like Alexandra Lex best. Not as fotced as some and really sassy. Bit left field but I knee a Monica nn Nic

Knew. I didn't knee her

Larissa- Lara/Rissa/Riss

Meant Lala, not Lara!

If you go for Allegra the nickname should be Leggy.

Eloise - Elle, or Ellie
Elizabeth - Beth
