I would like to have a page so people can discuss the differences because I know different people have different understandings. Here is my view. MTM - Basically a glorified ready to wear suit. It is machine cut to a pre-made size based on the clients measurments. Custom - Handcut pieces to each elements of the suit. Bespoke - Handcut as well with multiple fittings. Anyone want to add? This is just a quick reference.
