Choose a comfortable outfit that does not get you restrict you in any way.
For example, you can wear a warm wool vest, which you can take with you for a walk.
Choose clothes that are easy to maintain (for example, when cooking).
Wear secure and well-fitting slippers.
In the cooler rooms or at the cottage use quality sheep's socks and warmer Merino sheepskin slippers.
During relaxing activities - typically television, computer, reading, the ideal "warmth of home" is supported by a woolen blanket or a popular TV blanket.
