I don't know what fashion designer it is... need help? - what designer has a yellow eagle

I live in London, and very often I see these new bridges and smart shirts and a logo on the left side of the logo is an image of a yellow eagle with a black border, a few famous people often though, as Steve Jones ( Young T4) and Dermot O'Learey (Boy BBLB)
