i got this skin: http://www.ebay.com/itm/Camera-Leather-decoration-sticker-Sony-DSC-RX100-4008-Leica-Type-/271136771173?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D5070246254553655035%26pid%3D100011%26prg%3D1005%26rk%3D1%26sd%3D251144840198%26
and it actually makes the camera look better than stock. it grips well - good enough for sure, although maybe not as secure as a franiec or a flipbac for some people. i didn't apply the upper bit.
i removed a flipbac grip to put this on the camera and i have no regrets at all. it makes the camera look so classy.
