Meet the Chameleon Sweater, a top-down seamless pullover that fits the way a sweater actually should. With a 3D contiguous set-in sleeve construction, precise German short row shoulder shaping, and a signature decorative shoulder braid, this is the pattern you'll return to in every colorway.
Available in 12 sizes (finished bust 88–174 cm / 34¾–68½") with both a mock neck and crew neck option, and regular or cropped length.
What makes this pattern different
The Chameleon Sweater is built around fit. The back is shaped first with German short rows to create a trapezoidal panel, then each shoulder is individually sculpted giving you that rare combination of structured shoulders and comfort. Testers called it "the most well-fitting sweater I own" and said they received compliments on the shoulders specifically.
The decorative knitted braid at each shoulder seam is the quiet signature detail that sets this sweater apart. Worked in the same yarn, it adds polish without complexity.
