The tradition of giving leis to graduates has now spread to the mainland. Many graduation leis at stateside schools are designed to reflect school spirit by incorporating flowers, yarn, ribbons or other materials in the graduate's school colors.
Lei is a garland or wreath. More loosely defined, a lei is any series of objects strung together with the intent to be worn.The most popular concept of a lei in Hawaiian culture is a wreath of flowers presented upon arriving or leaving as a symbol of affection.This concept was popularized through tourism between the Hawaiian Islands and the continental United States in the 19th and 20th centuries.f due to allergies or other reasons a person cannot wear a lei which has just been given (for instance a musician who would tangle the lei in his or her guitar strap), the lei is displayed in a place of honor, such as the musician's music stand or microphone stand.
