My first response to that question would be if I spent more than I could afford for the bag.
However, one month ago I purchased a bag at Forever 21. It was the first time I went to the store and I saw a bag that was cute and cheap. Unfortunately, cute and cheap did not cut it. The bag has already fallen apart. I only used the bag a couple of times. When I pulled the bag from a pile I noticed that the buckle was broken. Later in the day I found a piece under my desk at work. Now I do not want to even look at the bag. I would rather spend more money on a bag that will last years, than buy something trendy and cheap.
