it would have fitted the average toddler
I can see that you have been outbid on a Lacoste Jacket, and have a bid in for a slim skinny jumper.
My money is not yours, so is it really OK, ask yourself? You have bought on ebay a teeshirt and jacket (the duck one), which would have fitted the average toddler, so it seems to me you are better off going to a clothes shop. You may live in a consumer capital of the world, but canny consumers can find clothes at the right price, especially in such a capital. I know you know what you like to wear, and I am glad that you do, but one advantage of being a student is that almost anything is allowed, tattered torn, whatever!
