first upper part is knitted from one side to other. Increases on sleeve are made in V-shape on top of them instead of near the edges.
then pickup stitches all around bottom edge and knit till long enough. Sides are asymmetrical and with increases they are little longer than middle part. Finish with I-cord.
add crochet borders: flat on collar, ruffles on sleeves, and long under the I-cord.
mixed up all the colors randomly.
