Mine arrived yesterday. Overall I'm very happy with it, but I do think there are a few issues. The fit for me was perfect. Literally, it couldn't have been better if it had been tailored for me, so I'm very happy about that. However, comparing it to the excellent images here -
http://www.startrekpropauthority.com/2014/06/special-photo-study-patrick-stewart.html - there are a few things which I think are noticeably different from the original. Obviously the addition of a zip and a pocket were concessions to practicality, but there are a couple of other things which don't appear the same from the construction:
On the original, the fabric on the interior (not the lining) changes from red to black underneath the yoke. On the Anovos version, all of the interior fabric is red, meaning that there is a small piece of visible red fabric around the neck opening.
The padded sections around the cuffs and waistband look too puffy. This may well settle down after a while, and from a repeated pressing. However when you look at the original you can see that the waistband (and presumably the cuffs too) show the topstitching on the inside as well as the outside - on the Anovos version there is another layer of interior fabric making these areas thicker than they probably should be.
On the front panel of the yoke, around the neck opening, the Anovos version has an extra topstitch, creating a 1\2" piece of quilting running around the neck opening. This isn't present on the original - the lines of quilting can be seen running all the way into the neck opening.
The quality of the reproduction is slightly questionable. It seems to suffer from a slight lack of attention to detail. For instance on the original, all of the rows of quilting on the yoke line up front to back, whereas on my Anovos one, they don't. Also, on mine, the cuffs and waistband aren't finished very well, making the edges a little irregular. The edges on the original are very neat and straight. You can actually see this on the pictures of the prototype on the Anovos site, but it is far more pronounced on mine.
Speaking of the cuffs, if you look on the images of the original you can see that the seams on the sleeve line up perfectly with the topstitches of the quilting on the cuff, on the original. On mine, the seams don't line up with the topstitch, and it makes the cuffs look a little bit sloppily constructed.
I don't want anyone to think I'm saying this isn't a great jacket. It is, and I will really enjoy wearing it. However, on the Anovos site it claims that this is a faithful replica of the original (barring the addition of the zip and pocket), following the exact patterning and construction. This definitely is not the case - there are some very big differences between the Anovos version and the original. I would say that the jacket is a nice piece to wear every day, but it couldn't be considered a replica costume piece at all. I also feel that at a $300 price point, things like the detail of the cuffs and the waistband and the yoke, should all be better than they are. For $300 I was expecting I would get something near perfect, whereas I feel like this looks a little bit sloppily constructed, which is a little bit disappointing.
