One would think we would all learn - when we actually find something that fits well we should always buy two! Of course, I rarely do that thus most of my bike gear is somewhat tired looking.
I did find a great long sleeved jersey last year from maloja -but alas the store that sold them is no longer. I do see that backcountry.com may have them in stock. HOWEVER they run small, I bought a large and I am typically a size 6 with a 34b/c chest
