In 2018, Antonina presented this collection again, but with new accessories and a new look. The designer also developed additional products for the "Tekstiili18" textile exhibition, also organized by Aalto University. In addition, several looks from the collection were presented at the "Fashion Friday" exhibition at the Kiasma Museum. It was the first fashion exhibition in the history of this museum.
