Other movies like this?

Most of those I can remeber has been said by other posters, so I may add:
- Thelma & Louis (women, not girls, but it's great).
- Mall Girls (film from Poland about teenage girls)
- Lollipop Monster (german film about 2 teen girls).
- Virgin (I didn't find it very good, but it's about the close friendship of teen Indonesian girls).
- Nana and Nana 2 (japanese films about two different girls who shares the same name, their life and friendship. Based on the awesome manga of the same name).
- Little Darlings (I LOVE this movie! Good old film about a girl's summer camp, a bet, a new experiences. A very young Matt Dillon is here!).
- Whip It (about a teen Elen Page who discovers the world of Roller Derby, alongside Drew Barrymore, Zöe Bell, Juliette Lewis, etc.)
-The Runaways (inspired on the realife of guitarist Joan Jett and vocalist Cherie Currie as teen rockers from an all female rock band. Lita Ford is barely shown).
- Foxfire (2013) based on the same book, but ambiented on the 50's. I think it's a british film (I haven't seen it yet).

If I can recall any other I will post it here.

Please excuse my terrible redaction, english is not my native language.
