Reality show star Jenni "JWoww" Farley of MTV's 'Jersey Shore', whose entire cast seems to be perpetually tanned to the orange-th degree, modeled her new swimwear line designed for Perfect Tan Bikinis last week.

The bikinis have a heat-activated silicone inside the fabric so that they stay in place even after the wearer removes the straps, meaning no tan lines are visible above the bust line. According to the press information about JWoww's Perfect Tan bikinis, the warmer a wearer gets, the more the silicon adhesive in the suit is activated, causing it to cling. Of course, not everyone who purchases this swimwear will have the same "accessories" as JWoww, who seems to be using her own silicone to keep her bikini top from slipping off once sans straps.

We're sure that guys' swimming trunks also get a little tighter upon seeing JWoww in a bikini, with no heat-activated fabric necessary.
