I recently purchased Bristol 6's Hem tape while shopping in LA a few weeks ago, and just tried it out yesterday on my looong William Rast jeans. They are a great length for wearing 4" heels, but with flats I had to shorten them. In the past I've tried different kinds of tape to shorten my jeans temporarily and it never worked. This hem tape really works! It is sticky and sturdy enough to shorten jeans great. I like having the option of wearing certain jeans with high heels and also with flats as opposed to hemming them. Bristol 6 Hem tape retails for $12.
