I like them, but they're rubbish for parenting small children, you can't crouch in them unless you have a long top on. Or a really really trusty belt. Or a long stretchy singlet that's tucked in.

I agree that 3/4 stuff seems to be mostly lo rise. Hm. Could you get a pair of high/mid rise normal straight leg jeans and then roll them up to be 3/4?
