We're all well familiar with animal print by now; it's been a general fashion trend for years and manifests itself on bags season after season. I suppose that the current trend for printing actual animal images on bags is a somewhat extreme extension of the classic animal print idea, but the finishing ends up being quite different. One's luxurious and often a little sexy, the other swings cartoonish and irreverent. You can probably guess which is which without much assistance on my part.
In execution, this trend skews similar to the odd trend of putting eyes on bags (and, notably, involves several of the same brands); simple totes or pouches emblazoned with a print that's intended to be the bag's defining feature. In some instances, though, the bags take the shape of the animals themselves, which means that they fit both the animal trend and the eye trend. I'd say you're killing two birds with one stone, but that might be a tad on the nose.
