Well, it holds up to underwear....lol. I would say it would work well on knits, but I don't think I would trust it on a woven because it works so nicely with stretch. Does that make sense?

I've used a flatlock on the side seams of polar fleece pants and those held up great and this is similar to that type of seam.
