T-Shirts, place your orders!

What are the pit to pits on the other size shirts? If they are all coming up almost a size smaller than normal, might some of us need to revise our choice of sizes?

The measurements are here:

The S is halfway between Small and Medium.
The M is most definitely Medium.
The L is still being test by hippy.
The XL big daddy wayne reported as being 'hipster cut' (smaller than expected).
