Does a TROFEO® 600 fabric suit and St Lucia = Cool Bridegroom or a sweltering clown?

[transition]

Hello,

I am getting married in September in St.Lucia. It's a low key affair - just myself and wifey to be are flying out there. A few questions:

*Has anyone had any experience of Zegna's TROFEO silk as a fabric for a bespoke 2 piece suit?
* Anything of a similar weight (super 130ish?) that people could recommend?
*Which London based personable, reliable tailors would people recommend? Ideally an older geezer who knows his craft.
*Is a £700 budget realistic? If no, what I am I looking at?
* Is my decision to go for a lightweight suit a fashion faux pas? Colour scheme tbc (based on Wifey's colours) but I am thinking black suit, white shirt OR light blue suit white shirt (white pocket square, black belt w/silver buckle, silver tie pin, black oxford lace ups both options). Tie colour tbc. Wedding is AM near the beach.

Comments invited - thanks in advance!

The budget likely is too small, and a black suit isn't appropriate for a summer tropical wedding.

Reports elsewhere say TROFEO silk is "breathable," but everyone feels things differently and nothing probably breathes better than unlined tropical weight wool.
