As a beginner tracky bottoms are not going to be ideal when you fall over and get them wet !!!
If you have mates who ski borrowing gear can be the best bet for your first time.
This time of year weather can be like a hot summers day in the UK or it can be hammering it down with snow and cold. Layers are the key.
I wear a combination of a HH base merino layer that I use for winter bike riding too, micro fleece if its cold and a breathable shell jacket with no padding. If its really cold I might put on a layer underneath the micro fleece but this is really rare. Wear a pair of salopettes and sometimes long johns underneath if its really cold.
So layers are the key :-)
