HoerevWomen Girls Short High Waist Pleated Skater Tennis School Skirt

Im 13 and im 8stone and im usually a size six in skirts what size would fit best?

Is there any stretch to it? Just because I need a size 4 to fit my waist but I always trouble fitting skirts like these over my hips.

I’m 5”2 ish and 13 . How long is a size 6 ? Would it be too short on me?

What size do you recommend for a 12/14? Is it true to size?
