If you're just looking for the frosted glass effect, try something like this. Basically it's just a high transmission value (for transparency/translucency) and a mid-level(ish) roughness (to make it more opaque - "frosted"). I added a bit of subsurface as well, but it's probably not needed. The "Bump Map" setup is optional too, but I just wanted to give some "micro-bumps" on the surface:
If you want more transparency (see through it more), you can try this setup. You can control the "frostiness" and transparency/translucency using the IOR of both the Fresnel and the Refraction BSDF, as well as changing the Roughness on the Glass BSDF.
