cerich:online or not get a custom cut, it is so worth it....
USIA has a sizing video you can view on their website.
Unless you fit OTR... then its so NOT worth it.
And you can't tell until you try one on. A DUI Medium CLX450 is cut to fit much tighter (they were until recently) than a Medium TLS350... even though the measurements on the DUI site are the same.
You gotta try it on.
Only then will you really know if you need to go through the drama of ordering a custom suit.
