I suddenly have the urge to own black and white vertically striped pants.

maybe it's because of Givenchy's s/s 2010 black and white patterned leggings that I have recently been drooling over?

or maybe the fact that they will elongate my legs? possible it is because I can resemble Beetlejuice...

...whatever the reason, I
need a pair.
this will most likely need to be a DIY project since there has been little help searching over the internet...plus, it will give me a little street cred.
now here is the question I pose to you lovely readers for anyone who has ever attempted such a feat: how would I go about constructing these pants? I'm assuming black stripes should be either painted or spray painted on white jeans/pants/leggings using stencils...would this be the correct way to make them? sorry I'm such a n00b!
