What will you be dressing your baby in when it gets really cold?

I have bought 2 snow suits. One is thick waterproof and the other is a furry penguin. For in the car I have thicker onesie if late and for day just take her out of snowsuit to go into car with a blanket

Vest and leggings as a base, then long-sleeved top and additional layers like cardy or coat as and when needed, then I can add or strip off depending on the temperature. Same as above regards the car though.
