Basically, I love this song, but I despise power chords so I made up my own : )
I play it on an acoustic

Intro Em Em C D x2

      Em                        C
Well, she's not bleeding on the ballroom floor
D                 Em
Just for the attention.
                    C       D
Cause that's just ridiculously odd
      Em
Well, she sure is gonna get it
C
   Here's the setting
D                          Em
Fashion magazines line the walls now
                         C     D
The walls line the bullet holes

Em Em C D

Em
Have some composure
G
Where is your posture?
C        A
Oh, no, no
Em
You're pulling the trigger
G
Pulling the trigger
C        A
All wrong
[x2]

Em                                              G
Give me envy, give me malice, give me your attention
Give me envy, give me malice, baby, give me a break!
C
When I say "Shotgun", you say "Wedding"
D
"Shotgun", "Wedding", "Shotgun", "Wedding"

Em
  She didn't choose this role
C                        D
  But she'll play it and make it sincere
Em          C    D
So you cry, you cry
(Give me a break)
Em
But they believe it from the tears
                    C              D
And the teeth right down to the blood
        Em
At her feet
Boys will be boys
               C               D
Hiding in estrogen and wearing Aubergine dreams
D
(Give me a break)

Em
Have some composure
G
Where is your posture?
C        A
Oh, no, no
Em
You're pulling the trigger
G
Pulling the trigger
C    A
All wrong
[x2]

Em                 G              Em  G
Come on this is screaming "Photo op." op...
Em
Come on
Come on
G
  This is screaming
        Em
This is screaming
                        G
This is screaming "Photo op."
