Its difficult to find costume clothes with this kind of quality. I shouldn't have to make everything myself to get a decent quality. I go to the Renaissance Festival once a year, and other various events. It's nice to find something that will stand up to time and the occasional abusive situation.Definitely buy one size smaller than what you're used to. I normally wear a large, & I bought a medium. A large tends to be almost too small for me. The medium that I got is about the size of an extra large. I probably could have gone with a small. But I was afraid that the arms would be too short. Honestly, I am glad I went with the medium. By the time I get a belt on and other things, it should be proper. I am 5'10" and have broad shoulders and a 34" waist. My arms are about 3" too long on each side. Consider that when sizing. This was a medium! Long sleeves and an extra large sized body area.Amazing quality compared to anyone else!I can't express that more! Compared to some of the garbage they pedal at the RenFest.... This is authentic. Great job!Well the arms are poofy!! This shirt was way more than I expected, it should be spectacular!!! I bought for a Mountain Man Rendezvous booth. I fully plan on using this in Scouts with a kilt, so I’m getting double duty with it. It seems well made, can’t wait to see how it does. Did I mention the arms are poooooofy? Sooooo poofy, should be spectacular. These shirts seems to be over sized to boot, I could have easily gotten away with a 3XL vs a 4XL (maybe even a 2XL) but I do love the way the 4XL fits me.Well made, good quality for the price point, arrived on time.This shirt is fantastic! They have a serious sense of humor on the care label too.
