Please 
DH is late 30s and lives in shirts! Suits for work and tucked into jeans with a jacket for casual. He only buys good cotton shirts with double cuffs and generally looks very handsome
. He's never been able to do casual, trendy looks. Tshirts come out for DIY or extreme heat but that's as far as he'll go. We've got a run of 40th birthday parties coming up and I'd love to get him something other than a shirt to wear with his jeans (which are actually very nice!). Any ideas would be very much appreciated.
