Majority of countries and designers represent their work in a small places all around the London. Displaying their work as well as a possibility of buying their designer works on place. But not everywhere.
It is very interesting, since it is split up by countries, so you will see each technique, designers and their cultural differences within fashion design.
I have so far visited 4 countries out of I do not even know how much (believe me a lot, and I won't be seeing all of them, because of school time)
