I knitted Sous Sous in Thames DK which is a luxurious blend of baby alpaca, Falklands Merino and mulberry silk. The jumper has a boxy shape with loads of positive ease. You select your size by measuring your upper arm circumference.
Sous Sous is constructed flat in two separate pieces before joining at the shoulders and picking up for the sleeves which are also worked back and forth in rows. Shaping row 3 in the Front creates the bias which in turn sets the shoulder shaping.
You can buy this pattern from the designer on Ravelry here.
