Summing up

15 degree Celsius outfits tips

The best way to dress in 15-degree Celsius weather depends a lot on your daily activities, but some key tips are:

  • Always have a clothing piece that you can easily remove and then put back on. You should expect some changes in temperature during the day, and having a coat, a blazer or a cardigan is the best way in which you can prepare.
  • Check the weather apps in advance and have a waterproof jacket or an umbrella if they announce rain.
  • Wear cute footwear that protects you. Taking care of your feet is crucial for your health!
  • Always look to buy basic clothes that are easy to match - this way you save a lot of time that you'd normally spend in front of the mirror trying on clothes that don't match, but also a lot of money that you'd spend on new clothes. When you no longer feel you have nothing to wear, you no longer need to keep buying. You will enjoy wearing the same basics in other seasons as well.
  • Do research and support with your purchases only the brands that you trust, that care about the quality of their products and about the environment.
