Pantyhose?? YOu couldn't PAY me to wear them, or buy them!

Ok, you say you bought some winter biking clothes, but you don't say what you got- that doesn't help us much.
In any case- for your legs in the cold, you could do several things:
Wear regular chamois shorts and then some non-chamois cold weather biking tights (footless) over that.
or wear non-chamois footless tights or leggings under some chamois biking shorts or chamois biking tights.
Or wear some chamois biking tights with leg warmers you can peel off when you get warmed up.
other than legs- wear wool socks (SmartWool socks are thin and warm) and wear some smartwool or 100%merino thin longsleeve base layer crew neck polos under whatever windbreaker or jacket or warm vest you choose. Wear either one or two wool base layer tops, and you can remove one mid-ride if you get too warm.

The trick is to wear several thin warm layers that you can take off as needed and then roll up small and strap to your bike and keep peddling.
100% THIN merino wool is really good- it's warm but breathes and wicks away sweat and generally it doesn't get underarm odor until worn several times over. A thin wool under-helmet liner head beanie is good too.
