Ich habe nichts zum Anziehen.
I have nothing to wear.
Usually used by persons with a full wardrobe, indicating that they have nothing to wear for a special occasion, such as going to work, to school or just out of their room with an undertone of: I really need to go shopping soon. Best yesterday. With a friend who can give me emotional support. And a lot of money. :)

I have found a few sentences for you to understand. I have nothing at all to wear= Ich habe überhaupt nichts anzuziehen. Look here: https://www.dict.cc/?s=anzuziehen
