Shirts
Mens shirts used to be an undergarmet that was worn only by men, however in popular culture the term shirt has come to refer to any upper body garmet other than a coat. The traditional mens shirt was long sleeved, had a collar, sleeves had cuffs and always buttoned down the middle of the front.
High class shirts often times have longer tails, sometimes the length down to the mans knees. These shirts are also made of a heaver, higher quality material than regular shirts. These types of shirts are typically worn to high class, white collar events, regular shirts are appropriate for most other occasions.
