Latex leggings keep rolling down at the waist, any fix?

Love my new latex leggings, but the waistband keeps rolling down on me after a while, especially when I am sitting and standing a lot through an evening. It is not the end of the world, but it looks messy and I keep hoiking them up like a teenager. Is this a fit problem, a gauge problem, or just how leggings behave in latex? Would a higher waist or a heavier gauge hold better? Or is there a trick to seating them properly so they stay put? I do not want to size down and cut off my own circulation.
