Yarnaby cosplay update

Help, how do i make him skinnier. I dont wanna wear platforms and my arms look tiny. Options: Remove 4 strands/color horizontally (currently 9/color) Remove every other layer (currently 7 will probs be close to 11 or 12) Last option remove all yarn, trim and sew shirt tighter then redo yarn about 5/color horizontally (not ideal but doable)
