The elasticity in these briefs is perfect & supportive.  I was not looking for the support like Spanks advertises but I got it with Wacoal & I love it!  I do not hand wash.  This product holds it's shape & elasticity through washing & has a long life with no pilling so far.  This is a very well made brief & the stiching in back is GENIUS.  Nothing shows under my clothing.  I could not be happier with these panties.
