I couldn’t find anything that really matched the look of Balenciaga’s proper WOC chain (it’s a box chain) or the color of the classic hardware (like dark patina’d brass) but I got this chain in antique gold and then sponged it with some black paint to “age” it, and am really liking it.
Note it does make getting into the zippered compartment a bit of a pain, because this is what the chain attaches to. And it will rub on the sides of the top flap of the wallet…I’m expecting I’m going to rehab those edges regularly! But I don’t wear it with the chain all the time…most use just as a wallet inside a larger bag most of the time.
