Columbia Sportswear Silver Ridge L/S Shirt

After returning the Medium which was extremely tight, I received the Large and to my great disappointiment, it was way too large. There must not be any quality control in the manufacturing of this item with such a discrepancy in sizing between 2 sizes.
I liked the way the cuff was cut on an angle to cover the back of the hand-very clever functionality.
Although, the tab that is supposed to button on the arm when the sleeve is rolled up was next to impossible to attach. the button is hidden under a tiny upside down pocket on the upper sleeve and getting one's fingers underneath to button the tab is impossible. Very poor functional design element.
I couldn't keep the shirt anyway due to the sizing issue. I am 5'7" 124 lbs, small bust.

I was debating between getting the Small or Medium based on the sizing specs since my measurements were a bit of both. I chose the Medium anticipating that the larger size would allow more body movement when fly fishing. I was surprised upon receiving and trying on the Medium how fitted and tight the design of the shirt is. I am exchanging the Medium for a Large.
I do like shirts with some fitted form, and not too baggy, but the Medium was too tight to even layer a t-shirt comfortably underneath. It was also too body clinging for hot weather when some air circulation would be helpful.
Otherwise, the shirt seems just fine and I look forward to trying on the Large. I wanted a light tan color and a functional shirt for fishing and safari in Africa.
I am 5'7" 125 lb.s with a narrow torso and small bust. I usually wear a size 6 or 8 in tops unless the cut is unusually small.
