If you’re planning to visit somewhere cold or planning a ski trip, you’re going to want these. I’ve worn them every day this winter in NYC. The nude base comes in lots of colours. This is a mid-warmth thermal. The grey are heat plus for super cold days! Wear the tights under trousers or on their own to keep warm. I got a medium in all these! LTKstyletip LTKSeasonal LTKunder50
