fraternity "little sisters" do they still exist?

<p>When I was in college in the 70’s the frats had little sister groups of women associated with them – not full members but available for parties etc. Is this still the case at universities today?</p>

** Some still do this. I think it is campus culture at some schools.</p>

<p>At my school, if a frat is having a fancier get together, brothers invite a couple of girls each, usually.</p>
