This buttock enhancer is a one piece panty with foam padding built right into the buttocks. It is molded and formed to keep its shape. Micro holes combined with super light weight fabric make this our most comfortable and cool padded panty. Perfect for the hot summer months. The light color is great to wear under white and make you feel comfortable and looks natural. This panty shows a natural curve with no lines, and you will not see the inseams under leggings.
