The other day was the 17th of May, which in Norway is a serious business. It's the Norwegian National Day or Constitution Day and it's celebrated rather violently compared to many other countries. This is just going to be a photo post, showing the national costumes Norwegians wear on this day. In general, people are rather happy if it's not too hot on the 17th of May since a big part of them walk around in many layers of wool. These costumes cost thousands of euros and each region has its own costume.
For those who party on this day, the festivities start at like 10 in the morning. The 18th of May is an ordinary working day, so it's a good idea to already be hung over by the evening, with the hope of having recovered in the morning.
There are plenty of flags on the 17th of May.
