Bermuda shorts and keen shoes.

Outdoor rule #1: Layers
Cotton is ok as long as you don't get wet. Most people overdress and get wet then freeze. It's far better to be a little cool at first than to get wet. I've been to -50F in cotton without problems however you have to be careful which is essential at that temp no matter what you're wearing.
32F is summer gear with the liners put in, jeans, flannel shirt and winter riding gloves. No other changes.
Good down into the 20's plus 60mph windchill for hours on end:
Thermal underwear, jeans. Air mesh overpants with windproof partiall insulated liners in. Gaters under the overpants if it's in the 20's.
Winter hiking boots with thick socks. Gaters improve heat retention. Overboots are available however not used.
Tshirt. Long sleeve pullover shirt and a flannel shirt. Fleece is available if needed. Kili air jacket with the windproof mildly insulated liner in.
Hands are the tough bit: Winter riding gloves. Overmits available if needed.
Half ski mask that goes down into the jacket. Nothing betwen my head and the helmet liner since my helmet is too tight for that. If it's that cold, I quit riding.
No skin exposure to the elements.
Plexifairing 3 windscreen does wonders at keeping the windchill manageable.
A backpack helps cut down on wind related heat loss.
I have no interior storage at all so the motorcycle is out in the elements year round. Getting the motorcycle to start at 20F is the hard part. Last winter when I only had the motorcycle for transportation, I used heat wire, the cover and a few pieces of 1" foam insulation for overnight preheat. (It being stubborn means it's smarter than I am sometimes)
Beyond that, I park the motorcycle and get serious.
