Style and Fashion class homework!

On Monday, girls have been given a homework to discover more about Fashion Designers! 
Girls from 10-13 years old who never heard before about designers like Iseey Miyake, Ralph Lauren, Marc Jacobs etc. Of course why would they if their mums are not shopaholics and brand obsessed  ones! :)  So they could not wait to find out more! So they happily took some homework to find out more about most popular nowadays designers! 
Just to top it up with some excitement, girls got to watch few Fashion Shows from Victor & Ralph, Victoria Secret and Ralph Lauren! So the shouts we have heard : " I want to be a designer!" or " I want to be a Victoria Secret Model! "
Now absolutely fascinated by the fashion and style they left the class and already next day they brought material they found which was due in a month time! 
Conclusion?!  
Perfect age for discovering the current fashion and beauty and release their creativity! 
Do you know who is this designed by?
