I seem to be riding a middle ground in this discussion.

During these summer days (temps. in the high 60's to work, mid 90's riding home) top to bottom: Helmet, skull cap (lycra), T-Shirt (cotton), reflective vest (some non-natural but-not-lycra material) real road cycing shorts next to my skin, floppy mountain bike shorts over the road shorts, cycling socks, 6-6-1 sandals w/SPD cleats.

So, neither Pro-Look nor Grant Approved casual.

Never a cycling jersey. In the winter I'll wear a base layer (wool or poly pro) and BMX shoes instead of sandals, plus jacket, knee or legs warmers as necessary, but otherwise as with my summer clothing noted above.

I have met Grant, and spoken with him at length, but never discussed commuting. Pity that! Next time (if there is one) I'll bring that up in our conversation.

My commute 8 mi. by bike, 11 mi. by Metro Train - each way.
