Love the classic style of this pattern! The largest size in the pattern is 18 mos., so I really had to modify to get a size to fit my 4 1/2 year old granddaughter. I used a larger hook and thicker yarn, but for a denser skirt like the pattern using the suggested yarn and hook, you could just go with more stitches and rows to make a larger size.

Modifications I made to adjust size:
Hook: 4.5mm
Yarn: DK (3)
Waistband: 12 stitches, 67 rows (2.5” wide waistband)
Rise: 42 stitches, 67 rows (length of skirt from bottom of waistband is 10”)

I am rating the pattern intermediate (medium) due to the technique used for joining the skirt to the waistband and the waistband button flap directions were a little vague for a beginner to understand. Experience with joining ribbing in the round is helpful. (I have made this hat before and found it helpful in understanding the joining technique used: http://www.ravelry.com/patterns/library/unforgettable-hat)
