A good <b>shirt</b> comes down to the smallest details - with such a simple piece, they&#39;ve all got to be right. And there&#39;s no need to fret when Swedish label <a href="http://www.selfridges.com/GB/en/cat/Eton" style="text-decoration: none"><font color="black"><b>Eton</b></font></a> has your back (or your back is sporting one of its shirts). Detailed with a micro-geometric pattern, this piece is cut with the brand&#39;s contemporary fit, an update on the 1950s classic but with darts for a slightly trim shape that&#39;s still got plenty of movement.
