Depending on where you're buying it, that measurement is speculative. Is it an MTM from a previous client? Is it RTW?If you actually measure 19.5 by a tailor, your chest is probably between 43 and 45 (a guess). A 20" p2p is usually seen on a 44 off the rack. Sometimes 44's have 19.5" shoulders but usually 20 to 20.5 even in the case of a canali or similar cut. If it was mtm and the p2p is 20", you need to ask some questions to see what the chest was, as well.
