Can anyone confirm whether Kooba alters the design of their handbags from season to season? I have two Kooba Ada's sitting in front of me - one I bought last year & one I bought this week. There are significant differences - the first one I bought has 10 studs down the front & has a different texture (like in the first picture). The second one only has 8 studs down the front & the leather looks different. I know the first one is authentic (bought it at Bergdorfs), so I assumed the second one was a fake (bought on eBay) - when I contacted the seller about this, she directed me to a picture of the Ada bag on the Kooba website. Her story is that the older Ada bags from the previous collection are a little different - more studs down the front & a slightly smoother texture. And in fact, the Ada picture from Kooba's official store looks like the bag she sent me (2nd pic). I've been surfing around the web this morning looking at different store websites & it appears that there may indeed be older & newer versions of the Ada bag - can anyone confirm this? I don't want to accuse the seller of selling fakes if it's not true. The pictures I've attached both come from authorized dealers, but the bags look significantly different. Does Kooba modify their designs?
