For J-rock cosplays use and ivory foundation. Just pure white looks fake and makes you look like a clown. And in the photos of J-rock start they use lights to give more of a plae look.
But I suggest using maybe a creamy textured foundation always since it goes on evenly and seems to look best. Ben Nye is very popular with some J-rock cosplayers but it is a tad expencive. u.u;;
