i reckon Ringo wouldnt have bothered with half the styles they did if it wasnt for the bandsi mage whole image - he seems like a nice short back and sides kind of guy and maybe a pair of cords.
Paul i reckon would be in to all the trends, and always at the cutting edge of fashion, but wouldnt go to extreme like (growing his hair to messy, or wearing unflattering clothing) at the expense of looking good.
John i think he looked the part but it was more for show and publicity, more trendy hippy with the white suits and that (more for show)
George seems much more than just the image, he seemed in touch with the planet more so than the rest and its energy. and his dress sense didnt seem forced.
