Query: Valeo Neoprene Waist Trimmer

Was not enough detail about this waist trimmer. I used it on the bare skin and had difficulty in pulling and keeping the ends on top so the velcro will line up evenly on top or the lower portion of the waist trimmer to prevent it from pinching the skin. If it had something to hold on to for pulling evenly that would make it a better product. If you plan on using it over the shirt it would be more pleasant to use.
