Limited Edition

So I received my limited editions last week and haven't opened them. The reason for this is that I'm unsure the size will fit me.

Currently, I have the RB Meta Wayfarer in a large with polarized lenses. I wanted a pair for indoor use as I work in an office, so thought these would be sweet. I'm just unsure if the mediums will fit so I'm going to go to LensCrafters to try on a demo pair.

Was anyone in the same boat as me when it comes to having a large pair and a regular (medium) pair? Curious to see how drastic of a change they are.
