I ordered this Caesar costume to host a party. I am a completely normal built man at 5'11" and weighing 190 lbs. (I have a fifteen pound gut that needs to depart soon). I normally wear size 42 regular jackets in the USA, with size 34 pants. Getting this costume to fit required several pinnings. The belt was way too large for my waist and the shroud was too long and would not stay set in the loose belt. The material was some cheap scratchy synthetic fiber and overall the costume was pretty cheaply made (at least for $30).  It was also fairly hot and did not breathe at all.

In all honesty, I have a feeling this was sized in some overseas factory by some manager who has no idea how Americans are built (and I don't mean just the obesity crisis). Overall, if you don't mind spending thirty minutes pinning the costume to make it fit better before the party, it will work fine, but it is not high quality.
