The world of fashion is always changing, and it's highly competitive. Fashion merchandisers may specialize in the arena of manufacturing, selling, promoting or buying. A successful fashion merchandiser has a vast knowledge of textiles (these are the different fabrics and fibers that are used to make the goods) and good communication ability. To stand out in the field, they need to know what people are looking for now and have an idea what they will be seeking in the future. This calls for first-rate people skills because they may have to correspond with people of various ethnic backgrounds, ages and lifestyles. In many cases, they travel around the world to obtain materials and meet with different clients and manufacturers.
