since that is clearly directed at me, no it's not a fad, it serves a purpose and going to stay I carry bifold wallet all my live and carry it in my jacket inside pocket, I never had a problem before, because when I withdrew from ATM I gave it to my grandma to kept in her bag, and I only have little cash with me to pay for petrol and small things I buy. now since I live by myself I have to carry all the bill and see the problem of bifold wallet. The money in it always look half folded and crumpled the more bill in it the more it get crumpled and in country with pretty much cash economy I carry a lot of bills and coins that makes my bifold exploded everytime I come from ATM. So I have 2 option, to get a better wallet, or to get a wife. weighing from past experience and career I pursue I chose the former. Since I moved to long wallet it is still a bifold but not a billfold, they are just flatter, and neater, even crumpled change money I receive get flattened and look much neater the moment I use it to pay to someone else since the bills are laid flat vertically inside and not folding along under the wallet spine, also a lot more slots for different bills, and receipts. Accidentally this transition happened when I also moved into denim thing 2 years ago, and so I bought this vegtan long wallet with clasp and concho, then I have 2 options, either I buy a veg tan man purse and put everything in it and carry it around, or put leather chain to it, and chose the latter and the wallet is natural color, so I want it to get darker too. I work in creative field, never wear suit, and work from home so that wallet is sitting on the desk 99% of the time and not causing me spinal problem so it's all good.
