Do me and my gf look similar?

Alot of my family and family friends and friends in general say me and my gf look really similar like one of my brothers friends saw a pic of my gf and thought it was me and im like wtf??

Like the only thing me and my gf say that we look similar is our glasses and that's it but other then that we don't see it. But what I've noticed it's always my straight family or friends that say we look similar.
