I would invest in one Hooter Hider or Bebe au Lait brand and use it as a template. They held up through 2.5 yrs of frequent use (I have teen stepkids and preferred to use it at home, too), as long as they didn't go in the dryer. The size was good, too, and the pocket was handy. The material was lightweight without being see-through. You might also consider linen as it is a very breathable fabric.
