Levi's Jean

My sister received Levi's Jean from her boyfriend. Levi's Jean is famous brand. I was happy, because my sister received it. My sister and I share clothes. We have similar body, but I am a little fatter than her. She said " This is mine. you can't wear it, because of new Jean." I was disappointed. The Jeans are very expensive. The Jean price was 280,000Won. I want to receive gift from My boyfriend, but My boyfriend is pool, also I am pool. The Jean is very pretty and good. I envy my sister. The Levi's Jeans' style is skinny style. Now I will exercise because I want to wear the Jean. if I wear the Jean, my sister will be very angry. but I will wear the Jeans anyway.
