I don't know what technique was used to apply the pattern to this fabric, but the application was definitely done after the t-shirt had been made.  Unfortunately there were obviously little wrinkles in the sleeve, yoke and underarm area when the pattern and colors were applied to the underlying white burnout fabric tee shirt, resulting in a number of white slivers showing up on the finished t-shirt.  Depending on how large these are and where they happen to fall, the end result can be acceptable or unacceptable.  The first shirt sent me had a large white slice in front where the left sleeve met the body of the t-shirt; it was large enough that it jumped out at you before you saw anything else.  It looked like a piece of white paper was stuck to the shirt. So I returned it as defective and they sent me another one.  This one also has random white slivers but they are generally smaller and not so in your face - so I am keeping this one - but still not really thrilled with the production quality.  It's truly a beautiful shirt or at least it would be without this issue.

If you look at the picture of the Waterfall shirt you can see the random white slivers - or go to the Prana website and zoom in and you can actually see the wrinkle that caused the white section.  The picture of the Spinach colored shirt doesn't appear to have this issue, but the Sunset shirt has the white slivers on the sleeve.  Also note that per the Prana website "The colors on Sunset Spiral Tee are reverse of what is shown; the top of the tee is orange and the bottom accent color is brown." so be forewarned that the Sunset shirt may not look the same as the picture.

If you can get one without the wrinkle issue, or one with more or less innocuous wrinkle problems, it's a great tee shirt but it's a gamble.

Size wise, I am usually a 10, very occasionally a 12, often a medium, sometimes a large but in this shirt I ordered an XL (this is my first ever XL). I could have gone with the large but that would have been very form fitting.

March 28 update: Amazon has posted new pictures that now show the actual color scheme of the Sunset shirt.  They have also posted new pictures of the of the Water color which make the "white slice" problem more obvious.
