Fashion trends

Maybe I'm just getting old, but can someone explain to me why these have suddenly become the must-have fashion item for teenagers around here?! 😂 Léon's pacing up and down because I won't drive him to ikea now!

He even sat checking current warehouse stock online and gave me a running commentary as the 60 in the Odense branch slowly went down to 3 over the course of the afternoon. Can you imagine the shame of it if he's the only one who doesn't turn up to school tomorrow wearing one? 😂
