1. Size guide for girls’ denim clothing

Age and height comparison

3-4 years old (height 100-110cm): suitable for jeans with a waist of 17-18 inches, and the recommended length of pants is 40-45cm.

5-6 years old (height 115-125cm): you can choose denim shorts or dresses of size 90-110, and the length of the clothes is calculated according to 50% of the height (for example, for a height of 125cm, the length of the clothes is about 62cm).
Big kids (over 7 years old): Expanded to 170-180cm size, suitable for tall girls.
Size selection formula and avoidance skills

Slimming rule: Choose high-waisted denim shorts (waistline is 2cm above the navel) + waist-revealing short T-shirt (length ≤35cm), and match with thick-soled shoes to lengthen the proportion.
Looseness: The hip circumference is 3-5cm larger than the actual size to ensure freedom of movement; avoid too tight design to prevent rubbing the skin.

2. Recommended denim fabrics and styles for summer

Breathable fabrics

Cotton: Lightweight cotton blend, strong sweat absorption and not easy to get stuffy.

Elastic waistband: Children’s jeans have built-in adjustable elastic bands to adapt to different waist circumferences.

Denim shorts set: 90-140 sizes cover 3-10 years old, match with the same color top to create a vibrant look.
Denim dress: Korean casual style (90-150 sizes) is suitable for daily life, and the waist design makes you look slimmer.
Pleated skirt: Active dye denim mini skirt, elastic waist + gold buttons, suitable for festive occasions.

4. Professional purchase suggestions

Try on points: focus on checking whether the seams of the crotch and knees are flat to avoid cracking during activities.
