I finally learned a secret about ordering my shirts after years of having them ride up my back and have the sleeves ride up my arms....special order these tall versions and you will be much more satisfied with its wear.  With these shirts both problems are solved since the shirt tail is longer and I can order a 35/36 instead of having to live with the 34/45.

PS The Jockey tall t-shirts pairs great with this or any dress shirt as it too has a longer tail to prevent the ride up.  Also there are extra long neck ties that wear better than the standard versions.
