Bespoke Tailoring vs Made to Measure (MTM) vs Ready to wear suits (RTW)

There are 3 methods when you need to buy a new suit

1. RTW = Brands from the peg.
2. MTM = Made to Measure, often promoted and misused as genuine tailored suits. Nowadays the standard for a 'tailored suit'???? Or are you fooling yourself here?
3. Bespoke Tailoring = a suit made by a tailor by hand. All features are purely made for you with your purpose in mind.

Let's call this performance engineering for people who see their appearance as personal branding and don't settle for less. What would work if you want and dare to make a difference and a value of your style? But what are the differences? How does it work? And what does it do for you and your look and feel? Much confusion is created nowadays by all kind of marketing and branding so people can not find the trees in the forest anymore. So a basic understanding of the suit making market and methods is a must for any man taking his dress style serious.
