Choosing My Client

When I first heard that we had to choose our own clients I thought it was a joke.
In a real life situation, you don't choose your clients...
Our tutor said it was to facilitate us and let us choose a brand that we are familiar with, so the project could be easier. But I was so stuck...
Anyway, after some research I came across a British designer, really fashionable clothes. Ted Baker, so English :)

The designs of other stores throughout the country are outstanding. I believe they would fit so well in Harrogate! When I looked at some of their clothes and the pictures of other stores, I just knew... He was going to be my client!
Now, although I like them, I know very little about them, so I need to start researching, getting info, getting images for my mood board and so on.
Today we were explained how to formulate a rationale. Things start to make some sense, but I need to roll up my sleeves and just do it.
Sketching, drawing in 3D, brainstorming, model making. Help.
