For me it does help if the first wicking layer is skin tight. Other layers, not so much but not loose either.

Have you considered the idea that you're overdressed for the commute? I like to start out cold - cold enough that I would be uncomfortable if I didn't get moving. After about 1.5 to 2 miles I'm warmed up and whether I sweat or not (before sunrise this time of year, around freezing) just depends on how hard I want to push it for the remainder. Your commute is two miles. Start out colder and don't sweat it.
