De-Matronizing a Sweater HALP

[ymer]

A Christmas or two ago I received this very matronly looking white sweater from my grandmother.  Of course I instantly thought of everything I could do to it, and then left it alone for going on two years... anyway, I'm still really unsure, so I thought I'd ask you guys!  How can I destroy this. 

Apologies in advance for the... er... 'chill' I seem to have caught.  It does show I suppose how thick the sweater is.  (You can see my nipples  )


I divided by zero.




Thoughts?
