Just jumping in here regarding the mini K and KP.. KP doesn't have the option for a strap, could that be the main difference?
That being said, your mini K is my dream bag! I LOVE that colour and fingers crossed they have one for me when I go in December!! Congratulations!
They recently changed the naming for KP and mini K and I'm still not getting used to it, lol. And it created a bit of confusion when I was in Hawaii as well. SA thought bag coming in shipment was a what they used to call mini K, now renamed K20. I initially decided to not get it, as I already own two. And what I really hoped to get this time was either a K25 or KP.
But it turned out what they were getting was a KP, now renamed to mini K, so I had to get it.
My SA says December is good time to visit. Waikiki has been doing very well last few years and supposedly even better than Madison. SA said because of this fact, Paris sends them very good inventory and even more during the holidays. And probably due to mostly Asian clientele, they have better selections of small sizes compared to other stores in US or Europe. My sis got her mini K, urm, K20, from Waikiki about a year ago from Waikiki and I got that gris asphalt during last Christmas. I think the chance of you getting one in December is pretty good.
ETA : They were originally scheduled to reopen at old location in November but now it is delayed to May of next year.
