Mousse is a dress pattern built all in rectangles, which means that almost no fabric is wasted. It has drooping shoulders, gathers at the waist and a fullness that makes it pleasant in any season. The pattern is very easy to sew, since it is only straight lines (except for the bias added along the neckline). Mousse is available in two sizes: summer, with short sleeves and a length above the knee; winter, with longer sleeves and a dress length at mid-calf. It is proposed in one size: it will have a looser look for the smaller sizes and will discreetly underline the curves on the larger sizes.
