You can see why I draw parallels with suiting. Tom’s ‘bespoke’ is rather like made to measure, where you get something made to fit you along a set number of measurements. ‘Couture’ is more like a bespoke suit – a whole new pattern is cut from scratch.
My current glasses are also like a good ready-to-wear suit, in a way. Tom said they fitted my face pretty well, with the eyes relatively central within the lenses but the width of the frame offsetting how close the eyes are together. The arms are a tiny bit short, though the difference between width at my temples and my ears (10mm) is very standard. The nose setting is not ideal, and indeed I have noticed that if I wear them for more than a few days in a row I get red patches under the pads. That classic round shape is called a panto, apparently.
