The Peekaboo debuted in 2009, and at first, it did what freshly debuted designer replica handbags normally do: the Peekaboo enjoyed a couple years of popularity and then got rotated to the back of the lineup in favor of whatever Next Big Things the brand had in the pipeline. Generally, that's followed by a bag being mostly ignored and then eventually put out to pasture quietly, when people are unlikely to notice its eventually absence. Instead of that slow march into the sunset, fendi outlet decided to reintroduce the Peekaboo and shoppers ate it up.
It's not unheard of for brands to try and re-promote a bag that was once very popular, but it rarely works. Shoppers want novelty, and most bags that are eligible for re-promotion just don't have the enduring appeal necessary to feel fresh instead of dated when a customer sees ray ban replica again, five years down the road. The Peekaboo has already passed that test with flying colors, and there's not reason to think it won't stick around for a long time.
