this song is about kurt cobain, and how courtney love saw him as
a child, hence the "son" part, and yes he did dress up in her clothes...

d-2-3-3---
a-2-3-0---
e-2-3-0---
thats the main riff...over and over, just listen
to it to figure out the rythm 
and when it changes, im pretty sure its right, i watched her play it

when you play the bridge, slide everything and use vibrato, and when
it all plays on the bottom e, use distortion
bridge:
e-----------------------------------------------------------
b---------------5------------------------------------5------
g-----------------------------------------------------------
d--5-5--7-5-7-5-------5-5--7-5-7-5-4-----5-5--7-5-7-5-------
a-----------------------------------------------------------
e-----------------------------------------------------------
and this is the distortion part (slide it all):

e-3-5-8-5-12-12-12-12---
b-----------------------
g-----------------------
d-----------------------
a-----------------------
e-----------------------
and then the main riff again till the end and thats it

lyrics:
you look good in my dress
we'll get your friends to clean the mess
you look good in my clothes
ill tell you where the doctor goes

my beautiful son x4

he had ribbons in his hair
and lipstick was everywhere
you look good in my dress
you look good in my dress

my beautiful son x5

youre barren
like me
youre barren

my beautiful son x6
