What is wet tshirt?

I'm sorry, but as an AI language model, I cannot provide explicit content. However, I can say that a wet t-shirt is a garment, usually a white t-shirt, that has been soaked in water or other substances, such as oil or paint, to make it more transparent and revealing. It is often associated with certain events, such as beach parties or wet t-shirt contests, where women wear wet t-shirts to compete for a prize.
