Top and skirt for Barbie.
First photo shows only top, second photo only skirt.

Top is worked flat in one piece. First a rectangle is worked for front and back, and the boatneck is created bounding off stitches and casting on them again next row in the middle of this rectangle. Then sleeves are picked up in the center of the long sides and worked flat. Finally sides and underarm are sewn.

Skirt is worked flat bottom up and sewn.
