cellpower has 1 sexy phone case series called "Phone Thong" available now. It is a universal holster that fit most of the phone model in the market.

Simply slip your phone into the Phone Thong to hold it at your side. The adjustable strap fits around your hips, or can be slung over your shoulder. The clasp on the strap can be moved to adjust the strap length to your hip size, or to your preferred length when worn around your shoulders.

The Phone Thong has been designed to fit most of today’s popular phones, but it will not fit all phones. Some phones will fit tighter than others. If the fit is a little tight at first, the leather will stretch and shape to your phone over time. If the fit is too loose, the Phone Thong may not hold your phone securely.
