Spa Clip for Towels

A clip element secures a towel or other cloth-like item around a person's body. The clip secures a cloth item that is wrapped around a user's body where one end of the cloth is flat against the wearer's skin and the other end of the cloth has been gathered and tucked behind the flat cloth and preventing separation of overlapping and tucked portions of the cloth item. Unlike previous clips where the clip exerts the pressure, the bulk from the cloth and the barrier that is the wearers torso, creates the leverage to hold the towel in place. The flexible bridge allows a user to pull out on the bottom front portion of the clip while catching the back portion of the clip behind the cloth on the wearer's torso to “thread” the cloth up to the top of the clip. Once the cloth knot (created from gathering one end of the towel and tucking it behind the flat part of the towel against the wearer's skin) is at the top rounded portion of the internal clip the cloth is being held by the pressure that is created by the clips fullness.
