Our total stretch wovens have been our best performers in this group. Newness is driving the dress pant category, which led our portfolio dress bottoms to have one of the best quarters on record with a plus-25% increase at retail. We have introduced new fabrications and constructions, and our fit offerings today includes classic, modern, slim, and very slim.
We're seeing performance fabrics, stretched gripper waistbands, and very slim fit as some of the top performers, which we will be expanding on throughout the year.
Original Penguin had a solid quarter with high single-digit growth of plus 7%. This performance reflects the success of our innovative product strategy with a push on new branding and logo-driven product. In 2018, we introduced five new versions of the Penguin logo with more development for 2019.
Innovation and product drove sales at higher retails, and we continue to focus on elevated distribution within better department stores, e-commerce sites, and specialty stores in the U.S. and Canada. In Europe, Original Penguin had an encouraging retail performance in wholesale and e-commerce with key young fashion retailers.
