As if we needed another reason to shop at Target, the retailer just launched a new collection of Lisa Frank pajamas that are taking us right back to our childhood days. Every item basically looks like the clothing version of those shiny stickers we stuck all over our folders and Trapper Keepers in middle school. The nostalgia is almost too much to handle! Each of the PJs involves the usual suspects: dolphins, unicorns, and tigers, all plastered against one of those signature psychedelic backgrounds we've come to know and love over the years. Ready to ditch your usual bedtime t-shirt and shorts for these technicolor jammies? Read on to shop all the offerings, which are now available both in Target stores and online — but act fast, because these items are selling out quickly!
