First of all, there is plenty of charming wallets on MR PORTER, you can find a lot of colors there and designs are interesting. For example, Marc By Marc Jacobs or Burberry wallets make an impression of self-made and fashionable man.
As we go further, I really love Paul Smith wallets. I found some on the Jules B website. Ever fought about upgrading banal black or brown wallet? Look through the Paul Smith designs with an enthrall idea inside it.
I'm adding some links from the websites I mentioned before. Next time while buying the wallet think carefully before considering, as I said, they really are your identity.
