Simply put, as the client, you have total creative control of your own bespoke tailoring creation. If one may be melodramatic about it, you are the captain of your own ship while the master tailor and the master cutter are merely your sea crewmen.
So the first task at hand to get a control of your ship is to muddle through a selection of over a thousand of cloth materials. Assuming, of course, you have enough gold coins to even consider the finest of them all fabrics that have been amassed and shipped in from across the seven seas.
The master tailor may be put to work though in detailing to you the qualities and attributes of the threads that you have been eying for your bespoke suits and fitted shirts. There are a variety of options to be had including cottons, pinpoint, royal Oxford, end on end, twill, herring bone, classic stripes, fashion stripes, checks, to name just a few of the thousand selections housed in the garrets.
Aside from the types of fabrics, color must be likewise given a careful thought on the crafting of your shirts. One can go for vibrant shades like lemon yellow, emerald green, royal blue or the neutral pastel colors like lavender pink, baby powder blue, and earth tones like brown and khakis. And of course, there is that standard and staple colors like the crisp whites and ebony black shirts.
As the captain though, you must be the one to steer the course of your own journey in bespoke tailoring. To do this, you should know where you are going in the first place and what you want.
