i have the striped billfold one and i love it. I reckon you should definitely get the striped one. The quality is, as you would expect, is second to none. I've had mine for 2 years now and it still looks relatively new.
I have a PS double billfold which isn't on there, and features an 80's personal stereo-boombox thing (A Sharp GF-777 I believe) printed on the inside. The quality is superb and it turns heads everywhere.
I would recommend the Naked Lady printed double billfold
This is such an unbelievable waste of cash, why not get a nice scarf or some gloves from there? Or a bag or something? I can't understand spending money on wallets, money clips on the other hand look far cooler, buy one of those
Personally, I think you could spend that much on a better brand then Paul Smith. Dolce & Gabbana, Hugo Boss and Armani do alot nicer wallets for that cost. I think Paul Smith is a bit of an older mans brand, but depends what your taste is.
