Making a Peek-a-boo Slip

If you're talking about a tummy control slip you might be able to find or order a less expensive one at Penney's or Sear's. Whether you're talking about a regular slip fabric or tummy control that has tulle on the bottom all you have to do is get an inexpensive slip of either sort in an appropriate length of any kind or color and sew tulle purchased from a fabric store to the bottom of the slip.

Look at several pattern books at a fabric store, I'm sure that you could find one.
