Plain & simple is likely the best option. Before sponsorship and corporate buy a new garish, hideous new shirt "design" every season which has just corrupted tradition club colours. It beats me how fans can be so gullible as to buy into this cynical money-making scam. I just wish young fans would adopt whatever they consider to be their side's classic kit, stick with that & deny the greed weasels opportunity to fleece them at every turn.
