Colorful kind of shirt (5)
I believe the answer is:
aloha
'colorful kind of shirt' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aloha that I've seen before include "greeting in Oahu" , "Welcome to Honolulu!" , "A Hawaiian welcome" , "Hawaiian "ciao"" , "A halo seen in Polynesian greeting" .)
