Hi, that's because there are two different size available at the moment, that is why some look bigger and some look tiny. Saint Laurent website has the Mini and Small available currently. They might introduce larger sizes in the futureThe Kaia bag is what drew me back to Saint Laurent and I started browsing their bags again. The Kaia seems large on some of the photos above but some others make it look teeny tiny! I wonder how much is holds? The soft floppy leather makes me believe this can fit a lot. I’m also hoping it comes in a slightly (barely) larger size and that the leather will darken in time because I find it a touch too light.
