Hi all.. I'm a newbie to Chanel. Just got some new sunnies this past wkend and now thinking of a bag. Planning on the GST in black. I know the GST is permanent...but I was wondering are both HWs always/readily available gold & silver to choose from?? Or do they only have one or the other that they release for that particular season. I know they release different colors of the GST. I plan on purchasing sometime before the increase a black GST with gold HW....just want to make sure it's out there since I prefer it over silver. Thanks!!
