Miami men wore breechcloths.

"A breechcloth is a long rectangular piece of taned deerskin, cloth, or animal fur.  It is worn between the legs and tucked over a belt, so that the flaps fall down in front and behind. Sometimes it is also called a breechclout, loincloth, skin clout, or just a flap." 

Due to the legs being left bare, Miami men wore leggings.  These were footless tubes of fabric to protect the leg.  They tied into the belt.  In cool weather men would sometimes wear shirts.  Leather moccasins were worn on the feet for foot protection. Instead of a headdress the Miami men wore a beaded headband.
