It's Warme Truiendag in the Netherlands today, which literally means warm sweater day. This day was invented to celebrate the Kyoto Protocol (an agreement between loads of countries to reduce gas). On this day you wear a warm sweater so you can turn down the heating or off. It's has been done a couple of times in the Netherlands and while they may have been loads of news articles about it. It's not really popular. To be quite honest, it's not particularly cold today but I suspect enough people will still have the heating quite high.
I made a selection of affordable and cute sweaters you can wear today. Enjoy your warm sweater day!
