Welcome regardemoi.
Under any conditions, that price for a T shirt is stupid. I could buy a nice guitar for that!
I understand why Alizée might be dressing down a bit if she is not featured at an event. It allows her to be there and not draw attention to herself. Some people might think that if she dresses up too much, that she is trying to take attention away from the featured people at the event.
The way some of these stars act, jealousy and bitching to the cameras and press might throw mud at Alizee unnecessarily.
