    No Shirt Pocket!
    Fit Type: Regular Fit, Color: Blue Stripe, Size: X-Large
    No Pocket! The material was nice quality, a little thicker than I would have anticipate for a low priced shirt, and very soft. The only disappointment was there was not shirt pocket. I suppose I did not look closely enough at the photos to notice that before I purchased. Otherwise, this is a very comfortable shirt.

    Fair quality all cotton Oxford with wide choice of colors
    Size: Small, Color: Sky Blue
    This is real oxford cloth with the warp dyed and weft left white. It's actually 100% cotton. I've ordered several other "100% Oxford" shirts on Amazon that were not. Amazon's own Essentials brand OCBD is better than this Cotton King brand and only half the price, but it is not offered in even a fourth of the colors. I like all the pastels. Amazon's "Stretch" version is not Oxford cloth or cotton at all. These Cotton King shirts are a bit lighter weight than the non-stretch cotton Amazon Oxford shirts which are about the same weight as the original Brook's Brothers or Lands' End "Sail Rigger Oxford" which is their current heavyweight oxford as well as their "Hyde Park" Oxford from the past. The Brooks Brother's USA-made Oxfords may be worth it, but I don't have a use for them. Their imported "Friday" Oxfords are just overpriced. Lands' End has been changing their sources and the fit is inconsistent often with sleeves that are too short and very few color choices. The all-cotton Amazon Oxfords are at least as good as the Lands' End and Brooks Brothers Friday shirts, sell for as little as Lands' End's lowest sale prices, and fit better, but the color choices are few. I've only bought these Cotton King in a few colors the others aren't offering. They're more expensive, but still half the price of the Friday shirts and worth just as much.
