I recently had the opportunity to test out a dress by Siizu, made from 100% tencel.
Tencel is a botanic fiber, and the eco-friendly tencel used by Siizu comes from Japan. It's super soft and has a great drape.
The dress that I had the opportunity to wear is the Zip Up Dress in pink. I received the sample size, which I'd been warned ran small, and I ended up altering it to a split-side tunic and wearing it with a slip to accommodate my curves.
I loved the feel of the fabric and the laid-back style, as well as the fact that it's washable. I learned that Tercel wrinkles easily, but it also steams out quickly. If you like eco-friendly companies, I'd recommend checking out Siizu for stylish, conscious fashions.
