My wife got me a DKNY wallet last year (or maybe the one before) that folds, has two pockets for notes, a flip up section with 6 credit card holders and a photograph holder, another two pockets which are credit card sized, and a button down coin pocket.
Just counted, mine holds 21 cards comfortably - although I never carry money in it, which makes more space.
Very nice and comfy - and it comes in black with minimalist chrome DKNY badge on inner corner.
Think it came from Harvey Nichols, or Jenners.
