No, no, no!
Marketers spends enormous amounts of money each year conducting extensive research on their target demographics. What lifestyles do they have, what type of jobs, what's their price point, what cultural icons do they respond to, what music do they listen to, what do they drive, how do they spend their leisure time, what's the competition doing and what can they do better, etc ... and once they have all that info, they tailor their marketing to grab the target customer's attention away from the competition. But, it won't work if their target market isn't interested in their product to begin with. For example, you could have the best, edgiest, most creative marketing ever to sell makeup and skirts to men but guess what. They won't go for it. At best, you might target the segment of aging men who feel they need to remain competitive in the work force, and sell them products to reduce facial lines and color the gray in their hair, all packaged in a nice, masculine looking box, because if it's pink there go your sales.
The only time you can create a demand is when you come up with a brand new product. Apple was very good with this. But, this is not the situation with the fashion or cosmetics industry. The best they can do is respond to their target customers' existing lifestyles. And successful clothing designers not only need to know current design trends, they need to have the ability to forecast future trends by being aware of what's going on in popular culture.
