I've seen some enthiusiastically, but not very accurately, rendered fan uniforms and I've seen some immaculate examples that could have walked straight off a bridge. I think the reasons that fans wear uniforms and how bothered they are by their accuracy is as varied as the reasons for wearing them. I've only worn a uniform once, back in the days of TWOK and even though I say so myself, it was very well done. There were about 10 of us, all wearing the same uniform from the same (home made) pattern, made by the same seamstress and cut from the same bolt of fabric. We still struggled with the pin holding the shoulder strap, finding the clasp for the front and the chest emblem, but we didn't care because most of the details were spot on, including the chain outlining the interior of the bib.
