If I did my costume today, I would instead choose Cosplaysky, though. It is the Imperial-only ESB/ROTJ pattern with nothing to modify and which is preferred by the writers of the CRLs. It is also in a lighter fabric which is more accurate, where as Mon Cal and Wampawear both use a more rugged fabric.
There are several threads on the JRS forums about Cosplaysky suits not fitting at all
- even if they've ordered a custom fit. And the commpad window is still pretty small and have to be altered by you. About the standard sizes, one thing always comes up; The top half fits good, and the legs are huge.
From reference photos I've seen, WW got it spot on. And they clearly keep track on the CRL, since the pointed collar was added on just recent.
