I don't give two shits what you are are wearing.
What really pisses me off is the fact that you are so ungrateful that your parents buy you things. You are very privileged and the fact that you think these purchases "dont matter to you because your not buying them" really shows how little appreciation you have for you very blessed life that you lead.
Rock whatever you like. Tall tees below the knees, one pieces, whatever. But regardless of what you wear, know that you are an extremely lucky person and that far less than 1% of the world gets to ski on a semi regular basis.
