It's Siepie! This year HEMA sold several outfits for Siepie and Takkie plushies. They had one for Sinterklaas, one for Christmas, and 2 winter outfits. One in red/white and one in blue/brown. We got both for Christmas! And we dressed up our (somewhat oversized) Siepie in the red/white set. While Siepie does not have hands, and therefore can't really wear mittens, I liked the idea too much to let it go. So there you have it, Siepie with mittens and socks!
