talking about my life/psychedelic grunge(core?)

my neck hurts a lot i think its bcz my posture sucks so bad. i dont know if a back brace would help but hey!!!! who knows. 

so anyway, i'd like to get more of like... a 60s look for my wardrobe?? maybe like a psychedelic grunge look. does anyone know anything about that?? like any clothing suggestions?? thnx!
