To the naked eyes, a suit appears to consist of two parts: a jacket and trousers. But those 2 seemily solid parts are composed of 4 different fabrics. Cotton, silk, mohair and wool. And those 4 fabrics are cut into 38 separate pieces. The process of sizing, forming, conjoining those pieces requires no fewer than 228 steps. So the 1st step is measurement, but "measurement" doesn't mean, just reaching for your tape, so many inches here, so many inches there. You can't make some thing good until you understand who you are making it for. All clothing says something. Who is your customer?and what are you trying to say about him? Is he timid, hunched over like a midday clock? or does he stand with confidence, spine at 6 and 12? Is this man of springtime pastel, clamoring to be noticed? or is this man of gray and brown, blending into the hurried crowd? Is this man comfortable in his station? or does he pined for grander things? and who would this man like to be? and who is he underneath? Take your measure, and when you understand who he is, then you are ready to begin.
It's not perfect, you have to make your peace with that. How? Well, you sit at your board, you lay out your tools, and you start again.
