A friend of mine went to Hawai (honeymoon trip) and brought some aloha shirts... They were not widespread here but one he bought (cotton,dark blue, white hibiscus flower) is a nice one. I was wondering buying one...Wise option or it's just some tourist trap and, in reality, no one from outside the islands use them? Cotton vs poly? There is any classic pattern(palm tree, hibiscus...)to be considered? Short sleeve vs long sleeve? Any thought will be welcomed...Thanks
