Hello and thanks for looking... This shirt is in nice condition. This polo will fit a L to an XL, the size is sort of in-between both. Lying flat it measures from pit to pit 22" and from the collar to hem is 27". I can't tell you much about this polo shirt, I just bought it today at a sale. Part of the original paper is still attached to the #1 on the inside, looks to be from Japan or China?. I'm not sure who # 17 is. Thank you for your interest in our item... We appreciate you and your business. I have two ebay sites, I'm not sure which one you're on but one is atapiyob and the other is jere32-27. Feel free to check them both out for similar items.
