JAKs are a chic shaper. Perfect for taming your tummy, hiding your muffin top and/or, my personal favorite, to hide what NO ONE should see, your butt crack. (sorry, there's really no other way to put it).
I own a few low-rise pants but they come with a problem when sitting or bending down but MissOops solves that problem JAKs look like a cami and no one has to know what they really look like. ;)
Also, they are made from 90% nylon and 10% lycra. Look at the beautiful lace fabric below.
JAKs retail for $20.00 but go on their website for current sales and promotions.
