I wear the ON Flirt and Diva jeans, although I was surprised also to find a pair of jeans at Target that have been my favorites for the last several months. I just buy them long and hem them (although be careful hemming because they will continue to shrink!) I found this really easy hemming technique online that allows you to keep the original stitching. This is one of a few tutorials online for the same technique.
