dealing w/jeans when switching between heels and flats?

I have recently discovered a great way to fix this problem, but it only works for straight-leg/skinny jeans. Instead of folding the jeans outwards, you can fold them inwards, and because the jeans are less wide, it just naturally stays without tape/staples, etc!! I hope this works for you! :nuts:
 
I'm short 5'1" so i have to have all my jeans hemmed, regardless. I typically have "flat/sneaker" jeans and "heel" jeans. I've fond in a quick pinch, duct tape will works wonders.
 
Well with my skinny jeans, I am just wearing them over the flat, even though they are kind of bunched up in the front. At first I thought it looked kind of wierd, then I looked at the way the celebs are wearing the skinny jeans with flats and now I am totally okay with that. I want to leave them longer because if I wear them with heels, I want them to be longer . . .
