I found that it was important to read the reviews as far as determining if these would fit.  Being a costume items you never know.  I am also 5'8" as another reviewer was and wear a size 6 or 8 normally.  These pants fit very good.  You could probably be shorter and not have any problem.  Wearing above a size 8 might be a bit tight.  The quality for a costume item was better than I expected.  I'm sure they'll be a big hit at the 60's party.
Glad I took the chance.  Shipping was super quick.
