Character clothing

I'm playing Team Fortress 2 and I would like to have some more durable clothing for my character. Can you tell me the best place to buy them?

As for me, it is best to pump yourself and earn weapons and clothes. But if someone wants to invest real money, then why not. Try going to https://tradeoffers.tf/orders/440 This is one of the best tf2 marketplace. There you will definitely be able to choose what you want to have for your hero in the game.
