A tropical outfit

I have read, many times, of chaps saying that it is not a good idea to wear a complete outfit because it looks OTT.

Well, here I am in a tropical weight suit, separate vest, panama hat (which is 26 years old), buttonhole, and co-repondent shoes. The question is does it look OTT? I suggest not.
Maybe, it is because I am used to such get-ups; the hat is a very old friend indeed and therefore I do not feel as though I am dressing up as such.
