I think you can be pretty confident that the TM Lewin collar is 16.25. Their returns policy means I wouldn't have any concerns about buying it and then returning it if you find it doesn't fit. Regarding the comparative sizing. the TM Lewin Fully Fitted shirts tend to be narrower through the chest and the waist than the Charles Tyrwhitt Tailored Fit/Extra Slim Fit, but this is not true for all collar sizes.
