(9/24/10) Overall, the costume is well constructed and assembled. The jacket is thick and feels solid. The zipper/button construction of the pants' fly is very convenient.
The greatest weakness of this ensemble, however, is the gross inaccuracy of the sizing in the hat and gloves. While the construction and details may be accurate to what was worn in the movies, the discrepancy between the sizing chart and the physical product is quite excessive.
I wear an XL hat, in baseball cap sizes. According to the published size chart, that is an XL officer hat. Upon receipt, it was far too large. I exchanged it for a Large, and that also turned out to be too big.
The gloves are superficially accurate, but also too big to be practical. The lining and padding are akin to business-class winter gloves. In the movies where the gloves are visible on General Veers or Captain Needa, the gloves are much more form fitting and thinner in construction. These gloves are also too large in comparison to the size chart and also too thick.
A secondary weakness to this ensemble is the rank badge. The product description claims twice that the customer has the option to choose what rank, but the order form does not allow that choice -- you get the 2x3 and nothing else. The construction of the badge itself is very good. However, the method of attachment to the uniform is quite poor: double-stick foam adhesive tape. If for display purposes only, then this method should suffice. If intending to wear the uniform more than once, however, it would behoove the customer to look into more durable methods of attachment.
UPDATE 2/22/11: I note that the description has changed and that it is now clear that there is only one option for the rank badge, and that the size chart for the hat now includes actual measurements. This is a vast improvement in the product description and is much less misleading. After wearing this uniform twice through my activities with a well-known Star Wars costume group, I am pleased to report that the construction is durable.
