I'd definitely vote to stick with the so-called 'short' sleeves. Longer sleeves always look a bit of a shocker. I feel for Patrick in the 131 fit pics, he looks swamped.
On a side note, IH shirts could almost always handle a trim in length too, 'shorter' shirts always look far sharper than longer shirts - again Patrick's pics do the 131 no favours, and that's an XS. I know everyone has their own personal preference, but I'd say at least 90% of IH shirts are an inch longer than they should be!
