The challenge with this collection is that it is made of sustainable fabrics—you can't do everything you'd like to do," Ann-Sofie Johansson, H&M creative advisor, says. "What has been a challenge up to now has been all the decorations. All the pearls. All the beading. We've had big progress and hopefully we can take that further and develop even more there." We see this design evolution Johansson speaks of in another impressive piece in the collection: a high-waisted silk midi skirt with art deco embellishments made from beads of recycled glass culled from factories.
