It's harder to be friends with girls in real life when you're a girl. O.o;
Personally- I find that A.) It's really annoying when they kind or rip off who you are and try to wear it like it's the new "Prada" bag or whatever girls wear. (Kind of like Batty said.) .. (-I don't usually have this problem.. I shop at the boy's section because their t-shirts are so much cooler D<)
B.) O.o; There's always that awkward moment when you like the same guy D<
And your friendship suddenly goes "OH HAI MR.WINDOW! LET ME HURL MYSELF OUT OF YOU!" which would be awful because- Like your boyfriend probably feels. You'd feel like they're trying to steal him away.
C.) They like to do these long ass fashion trips D<
Not sure if you're the type of girl that's into that. But I know- I refuse to go shopping with females O.o; Because they can't just Pop in and out and make up their minds D< Even if they go rarely.. It's for what feels like endless hours.
D.) Some of them are super-duper freakin sensitive D:

But- it is sorta nice to have the female conversation with someone about hair, and what you want to do with it. O.o;
Maybe- Honest to god try and wear super cute outfits. Not joking D< If you go to places regularly, and you see the same females there consistently. If you stand out, they might compliment you and WHAM BAM! New best friend xD

O.o; Note: I'm solely basing this on A.) being in highschool, and B.) (the compliment thing) because I have people (usually ladies with kids though..) compliment me and strike conversation, because I have t-shirts their kids like or junk. xD If you dress all cute like and stand out ish, you'll get noticed by girls, your guy friends might think it's weird but oh well.

OH OH OH! Try and go to a bar with the guys : o Maybe have the guys bring girlfriends, or like- O.o; Maybe have them lure in some girls? xD
Not sure if you're old enough to even drink. xD But I'm assuming so! But cha! : o And if you're looking for that Soul Calibur Heroine! Video game stores. The Females that work their.. Wicked awesome. xD
Same with Females who work at Hot Topic o.e; (If you're American).
