The photo shows two men standing next to each other. The man on the left is wearing a suit and tie, while the man on the right is wearing jeans and a jacket. The joke is that the man on the left looks like he's trying to impress the man on the right with his fancy clothes, while the man on the right doesn't seem to care much about appearances. Here's the joke in Turkish: "Sol taraftaki adam, sağ taraftaki adama ne kadar şık giyindiğini göstermeye çalışıyor ama sağ taraftaki adam umursamıyor gibi görünüyor." This translates to: "The man on the left is trying to show the man on the right how stylish he is, but the man on the right doesn't seem to care."
