Once upon a time, I promised a tutorial on how to unravel a discarded sweater for yarn. As I happened upon an untouched knit when looking for something in my stash, I decided today is the day.
On the shoulder, OK.
On the sides, never.
Buy it, take it home, toss it in the washing machine, and take it outside. Outside because unravelling is dusty work. Taking the knit out of the house saves you a whole lot of hoovering.

See the edges of the pieces?
Look for this.
The industrial straight-stitch machine leaves a crochet-like chain of stitches. The easiest way to undo this is to find a long end inside a seam, cut it, and pull at everything to find the end that unravels the whole seam. Once you find it, you can just pull, and watch the whole seam come undone.
Undo all of the seams, pull off collars and buttons, and you should end up with pieces that have at least three intact edges.
Find the end of yarn in the cast off edge, and start unravelling. Wind the yarn as you go along, since it will get tangled up in no time. I usually frog as I knit, but winding the yarn and letting it sit for a day or two will ease the curl.
