All about the cold and clothes

Ahh, I don't have enough clothes for winter! I had only just bought clothes for autumn and now it already feels like winter. The school is sooooo cold. Japanese schools are so mean because they're not well heated except for the staff room! I have an aversion to very thick and heavy clothes though. Just looking at those clothes make me feel sick. And what am I going to do with them if I go back for good??
