No specific yarn or gauge is given in the pattern, but we can tell that:
_ Sticka till Barbie patterns are usually designed for 4 ply mercerized cotton yarn or other fingering yarn.
_ The fluffy yarn to be worked with 4 mm needles is probably Sirdar Boa, and suggested gauge with this yarn is 20 sts 27 rows in 10cm.
_ Using 2.5 mm needles means that gauge for skirt is 28 sts 39 rows in 10 cm.
_ Using 2 mm needles means that gauge for body is 32 sts 44 rows in 10 cm.
