Basically what it implies: a crown made of flowers (real or fake). There are many different types and are very aesthetic. Many girls who wear them are assumed to be basic or hipster, but sometimes this is not the case. Flower crowns are amazing and lovely to wear. Don't let anybody insult you just because you enjoy wearing them, because they are wonderful and so are you.
Person 1: Omg I love your flowercrown!
Person 2: Thanks! It goes really well with my outfit.
