I Help Choosing A Designer Bag For My 15 Yr Old?

I want to get my daughter a special handbag(just her 15th birthday) as well as a christmas present. She mentioned something about liking pink prada messenger bag?People have reccomended labels such as Coach, Louis Vuitton,Vera Bradley,Prada, but I wanted to get from a young person’s perspective what would be the best choice. Price is not really a factor in my decision more of style and quality. Any suggestions and links would be great.
