It should be on sale too.
It's also available at Barneys in multiple sizes at a pretty hefty 25-30% markup.
EDIT: It's not the distressed one though.
And at half the cost of Barneys, the same non-distressed one on Farfetch.
^Weird, no joke, I've seen so many black 5 zips on sale, even on YOOX so many times @ like roughy $1,200 Aud (but also tax will also be included, so it would end up being $1,400?), I even came across a 48, the very boxy one, 2005 there abouts. It's amazing how yoox has such old stock, sometimes baffles me (I just got a Raf simons shirt from them, ss 2005 collection)
Anyway I guess Mrporter for Australia site no one gives a crap about the black 5 zips, all sizes always make the sales, its the colored ones that usually go weird enough.
Hell even all the whites are there since sales started, nothing has budged, currently only the IT56 is sold out lol, every other size is there.
I'm guessing they don't go anywhere cause Australia site has a higher markup compared to US prices as well.
