Hi there,
 
At my last institution we used a lot of forms, male and female.  With men's clothing, what we found worked best was to get child size torso's on stands.  These were usually loaned to us from area merchants.  Since people were smaller back then it was a better fit to get the smaller form.  Contemporary sized mannequins or torso's are too big usually.  When doing full uniforms with pants we ran the stanchion down the leg and stuffed them with acid free wrapped batting.  Again, the sizes were too hard to nail and we didn't have the budget to procure bodies that would work only those uniforms.  Using forms on stands also allowed for us to alter the height and make the exhibit flow a little better.
 
Hope this helps,
