Ephemera used his own skins in his pictures, they are called
Teru_K here in MTS (includes 8 skins but 2 newest are for Sims 3 so pay attention when grabbing them) but they also used to post to their own, now defunct, site + few Chinese forums. The files have been backed up and reshared by
Sims2packrat or more specifically by me back when I still ran it
I'm like 99% sure that particular skin is
E-Skin FMW Fixed.
