The attire the child is wearing is not Hawaiian but Micronesian. I recognize this because I grew up in Guam and have many Micronesian friends. I also lived most of my life in Hawaii, went to college in Hilo and first-hand knowledge of the culture.
It is a beautiful picture and warming to my heart. This brings back many memories of island culture which I love and miss. Mahalo nui loa zan si yuus maase (thanks in hawaiian & chamorro)
