The men also often wore slicked back hair that was short on the sides.

Answer 3

the 20's were called the "roaring 20's" because of the party atmosphere that characterized the decade prior to the great depression.  Women wore short (for the day) dresses with lots of tassles hanging.  they were called flappers.  Men wore suits called zoot suits.  do a google search.  zoot suits were high waisted, the coats had long tails and usually has a watch chain attached.  a hat ompleted the outfit.  like i said, do a google search for images of zoot suits.  should give you a good idea of what the look was.
