Where would you insert elastic or take a tuck in a pair of jeans that sag/bag at the back of the waist, they are stretch skinnies and fit my bum but the waist is way too big (bit of out of proportioness going on here). I normally just bung some elastic in the back, but would it be better to put it in the sides, so you avoid the bunching at the top of the bum?
Any clues/hints/tips, apart from reducing the size of my bum so I can buy smaller jeans lol.
