"The Prism Dress is a modern, raglan sleeve dress that is meant to be worn with some ease in the bust for a comfortable fit. It is fitted at the forearm, with minimal waist shaping, and a straight skirt for a sleek, fashion forward look. The hem hits just above the knee so this garment can be worn as a dress, or over pants or leggings as a tunic.
This dress can be made from a variety of fabrics including linen, wool crepe, double-gauze or voile so you can use the pattern over and over again! Sew it out of a heavier weight linen for a winter dress, or out of light-weight Khadi cotton for summer! The Prism Dress is a great garment to wear under knit sweaters and accessories, and the slim sleeves fit into your sweater sleeves easily."
