I think I've got it. :p

I got this men's bike jersey in med. It's made for twig men! I freely admit I have biceps and triceps. It's snug, but not overly tight around my arms. I'm a 36A, have shoulders and back muscles and again it's snug, but not overly tight across the chest.
I was most concerned when ordering it, about the elastic at the bottom. But this is actually sort of rubberized and I think will be less likely to ride up then my other elasticized jerseys. The length is good - the jersey comes down six inches or so below the waistband of my tri shorts.
I'll pair them with a pair of the arm coolers.
My plan is to put the jersey and arm coolers on at T1 and swim in my bra and shorts (and wetsuit as needed.)
