Ah my mind is racing in circles every time I come back to here and read more. More and more information such a wealth of knowledge. Difference in style (in this case the number of button on the front of the jacket) does not necessarily indicate quality. It is probable that lower quality may have fewer button as a cost cutting factor, but a high quality bespoke jacket may have only one button as a matter of style.

I was also foolishly under the impression that bespoke and made to measure were interchangeable. Before I put my foot once more into the mouth I went out to check, oh foolish me. I found and interesting bit of information at "English Cut, thomas mahon, bespoke savile row tailor, london."

This is intended to be a general comment and not a comment on the quality of any item available by any of the vendors that support this site.

See if I can paraphrase the different type of jacket constructions, see the above article for more detail.

Off-the-rack or Off-the-peg - Machine made to a generic pattern for a generic size. Every size 40 R will be the same size as every other 40 R in that pattern

Made-to-measure machine made and takes a generic pattern similar to the off the rack and make some modification to the customers measurements.

Hand-Made-off-the-rack or off-the-peg - hand made but still using a generic or standardized pattern not custom measurement.

Bespoke - Hand made to your measurements using a large number of measurements compared to made-to-measure.

It could be said that the quality of the garment increases as you go down the list and this would not be an unfair statement. I doubt you could compare the fit and feel of a bespoke jacket to fit and feel of an off-the-rack jacket. But at my age by the time I could save up for a $3,000 - to $4,000 dollar bespoke jacket I would be one good looking corpus.

As an alternative the article suggests that a jacket in a slightly larger size be purchased and have the fit adjusted by a local tailor. From what little experience I have here find a tailor and talk to them before purchasing the Off-the-rack jacket for their comments.
