If you find yourself there, by all means don't make a special trip out of your way!, I'd love to know which size has 15" shoulder span. All my jackets here measure that across the back from shoulder to shoulder, with 34" armpit to armpit. I could fudge the pit part if I didn't button, but when shoulders get smaller than 14.5" it gets snug. Length from collar to hem would be handy, too.
Again, only if you are already out and about! Thanks
