Men's Dress Shirts

The first number is your collar size in inches, and it is the finished measurement of the collar itself, so a 15.5 suits a neck of about 15 inches and leaves roughly a finger's room inside the band. The second is sleeve length, measured from the centre back of the collar over the shoulder to the cuff; 34-35 covers both lengths so one shirt fits a range. European labels give a single number in centimetres for the collar only: a 15.5 is a 39 or 40, a 16 is a 41, and sleeve length is fixed by the maker.

The difference is the angle between the collar points. A point collar sits narrow, roughly 60 degrees or less, and suits a slim knot; because it carries the eye downward it flatters a rounder or broader face. A semi-spread opens to around 80 to 90 degrees and takes almost any tie, which is why it is the safe default. A full spread or cutaway opens past 120 degrees, leaving room for a wide Windsor and adding width across a longer, narrower face, and it still looks deliberate worn open at the neck with no tie at all.
