It is very different.
In Milan there is huge "show" activities, FW is big, top level show room etc...
there are of course also some top edito, but under the top edito there are not that much magazines which produce interesting editos...
London, show activities is smaller, but there are more print work, and which can be interesting and creativ at different levels.
So Obviously girls better for print, Milan is not the right place for them, in London, some girls who are not that great for shows can still expect to have great jobs. London agencies are a bit less afraid of trying "short" girls than Milan for exemple...
