What's the general consensus on trenchcoats here (from burberry especially)? Are they on the casual side? I would've thought they are supposed to be an overcoat but I see most of the photos they have are worn without jackets, right on top of shirts. I thought they would be good for rainy weather that aren't too cold ie autumn etc where rain/wind may pick up but it's not freezing.
Really want this one to wear semi casually: http://uk.burberry.com/mid-length-cotton-gabardine-trench-coat-p38946931
But seems like it wouldn't be very versatile.
