Clear out my dated Milan info not long ago. Didn't sample as timing didn't work out.
In terms of clubs,
www.nightclubgattoverde.com &
www.peepshow-italia.com. We were told mostly EE girls. We stayed few street south of the main train station, like most EU train station, in the back streets plenty of Street girls, thou mostly gypsies.
Not sure if you're into Asians. One night I did have the urge call few agencies claimed to have J or K girls, when pressed, Flippinos pretend to be J.
Be sure to checkout Plazza Duomo, lotsa eye candy. Saw a high class girls out shopping, sexy blonde trying on boots, another at the cafe not far from LV store.
Enjoy Milan.
