We've all heard of G-Strings....but C-Strings? Yup! Just when we thought every kind of panty had already been invented, they come out with this C-String Invisible Underwear, $21.

Before you freak out, give me a minute to explain the photo on your right. Instead of having to deal with annoying underwear lines, this C-String provides coverage without the panty straps. You can even wear it in a tanning bed (tisk) and you won't get tan lines!

Your eyes are not playing tricks on you. Here's how it stays: C-String has a flexible internal frame that hugs and holds it to your body. At the front it looks like a normal sexy underwear and to the rear it has a thong-style strip.
