I love the vibe from all the FC locations. The staff are passionate about their designs and their colleague's designs, everyone seems to have the client in mind. They want us to look great, feel great, and be happy every time we visit, whether we buy something or not. I never feel pressured to buy anything, and I know I'll get an honest opinion when I try things on.
I also find that complete strangers will give their two cents to women that come out of the change rooms, which just solidifies the community feeling.
They mix up the display in the front to give each designer a showcase every so often too, which I think is really cool.
