    Love these

    Love these underwear so much, they are my everyday underwear now. They give me the confidence to wear whatever I want and not worry. They will stretch a little after a few wears just like other brands that make these bonded seam (invisible) underwear. So if between sizes definitely size down and break in for a couple wears.

    Excellent alternative to a panty liner

    Very comfortable. Great option without a panty liner - doesn’t feel like you’re wear anything!
