Lovely fabric. Neckline is fairly deep without showing cleavage. Only issue is a typical one for lightweight merino - not sheer, but does cling to the nooks and crannies a bit. This shirt is definitely comparable quality to other merino brands, at a fair price point (especially for being made in Canada). I am 5'9", 45" bust, 51 yrs, about 185 pounds, and XL is a good fit.
