How can one systematically relax the tension on the elastic band on tights, underwear, whatever? I have tried everything from excessive heat, exposure to sunlight, tieing weight to the band while hanging them, you name it. So far results of my tests have been a disappointment from completely relaxing the elastic permanently, to temporary change that is lost in the first wash cycle, to no change at all.
So why did I buy them so tight, you ask? Well I have a 33" waist and I have bought everything from medium to XL. The medium are perfect for a little compression, large perfect for relaxed comfort, but in both the elastic band is torture. The xlarge is only good because it provides a little relief (but not much) from the elastic band, which I am convinced was an invention of the devil.
