Fine merino knits actually do tend to contract a little when you wash them, but that's different than shrinkage (temporary vs. permanent). It's typical, in my experience, to have them tighten up on you and then stretch back out to the normal size after a wear or two. When it's wet, be careful not to stretch it out before it dries, though, and dry it flat. You should be A-OK.
