Fill this with black..this is so the lines we're going to create are visible.
Create a new blank layer, and with the line tool set at about 3px......draw 2 lines like so.
Make these right in the centre but not touching the top........merge the 2 layers containing the lines (not the black layer) then duplicate twice.....move these new layers either side of the original.
Now hide the black layer and hit "edit" and "define pattern"
Give your pattern a name , we will use this new pattern in the next step.
Now on to making the pinstripe material for real now....
create a new file and fill with any colour you want.....here ive used black so you get an idea of how your stripe will look......this texture is 512x512
Now right click the layer and go to blending option-pattern overlay
Play around with the opacity and scale sliders, until the pinstripe looks the way you want it.
Which gives you something like this
You can then use this on torso's for jackets legs for skirts or pants etc...
have fun with it..play around with the line lengths and placement while making your original pattern for different effects.
Make them diagonal or create small cross shapes...the choice is up to you.
