For a girl who's interested in fashion, what would be the dream job for success? Being a model? Probably no—?that's for a pencil thin who doesn't eat.One answer is, fashion stylist (时装造型师).

As more brands open stores in China to enlarge their reach, the increase in outdoor advertising might light a stylist spark in a girl' s heart.Fashion magazine offices are crowded with applicants, and fashionable brand HR managers get thousands of resumes (简历) of people looking for a stylist position.

"It looked too high before, but now I find it more approachable," said Xue Rui, 22, a Fudan University Chinese literature grad who works as an assistant stylist at Hermes in Shanghai."There is no certain rule in dressing up models, and you can try every way with your own taste to make them pretty and attractive."

The attractiveness of this line of work is not only in the elegant clothes.And it's not like it used to be.Now it's a well-paid and promising career.

"A stylist at a fashion magazine can have some special rights.You have a chance to contact (联系) famous persons and dress them up in a style you like," said Cheng Hong, chief editor of the Chinese version of L' officiel Hommes magazine." You need to cooperate with top photographers and select places around the world to take photos in.You might also be invited to fashion shows of top brands and can select some of the favorite clothes."

Girls can find it hard to ignore this field and it is opening up to normal girls, not only style or fashion design majors.A fashion designer knows how to make a dress pretty, but a stylist knows how to make a person beautiful, from head to toe.

There exist some problems, no matter how great you may think it is, it' s unbelievably hard work.You need to build good relations with various people, say stars, photographers, PR managers, other media, and even airlines.You need to take care of clothes in the workplace and pay for even a tiny spot you get on them.The worst thing is that you might work extremely hard for a week on some serious photos, but if the chief's not satisfied, you do them all over again.

So, remember, girls, you've been warned.
