From FibreMood:
Clemence's relaxed fit makes it a jumper you won’t want to take off. The 80s revival gave us a perfect reason to add a round neck and funky pleats at the top of the sleeves that playfully highlight your shoulders. With ‘too much is never enough’ as our motto, we're convinced you'll sew this jumper more than once.
Fabric advice
Clemence works best in knits. A fine knit fabric or knit jacquard are sure to do the trick. On the other hand, French terry, interlock, and sweatshirt fabric are also great options. If you go for a thicker fabric, be sure to use (rib) trim fabric for the neck, wrist, and hem bands.
