I'm the same height/weight, although a size 40. My 3A and 6A are both a size 42 and quite tight. When I take the sweaters off at the end of the day, the shirt I'm wearing underneath is wrinkled like crazy - esp. the sleeves. I don't consider that an issue as I don't take the sweater off during the day, but I can't imagine not sizing up at least one size. In addition, the length works perfectly for me - but someone taller may have an issue.
