Thanks a lot anyway, at least now we know.
I have another question though,
what about hair colours ? Is there a way to reduce the amount
of space "waisted" on hair colours ??
Lets just say this is my sim,
when she is at home studying:

Here she has done her hair, ready to meet some friends:

Back at home watching TV:

There are so many nice hair styles to choose from,
but to avoid "my sim" having to dye her hair before going to meet her friends
and then back again before watching the telly, it would be nice
if they all could share the same colour scheme. Of course you can have recolours,
but imagine the size of the downloads folder !!
So my question:
Is it somehow possible to reduce the amount
of space "waisted" on hair colours ??
