They Could Be...

Hey guys! Love all the people you've come up with so far, but I'd like to ask for some help myself! So! What I'm looking for is:

Fraternal twins (1 male, 1 female)
Early 20's
Brunette
Look somewhat similar because even though they're fraternal, it'd be nice if they had some similar features!

Other than that, GO HOG-WILD! Please and thank you!
