I have ridden 7 winters here in Great Lakes Region, 17-20 miles roundtrip each day, some winters can be very harsh. I don't use any cycling specific clothing... I use athletic-sports clothing, my favourite brands are North Face, UnderArmour, Adidas and few other brands which make merino wool clothing.
You don't need cycling clothing to ride your bike. My athletic-sports clothing is made from the same fabrics as cycling specific clothing, the only difference is that it's relaxed fit instead of skin tight and looks normal when in public places. I can't stand the look of cycling specific stuff, especially the shiny bright stuff. No need to walk around looking like a superhero. If I want to be visible then I just put my ANSI hi-visibility traffic shirt over my regular dark clothing.
