Gentle Care for Growing Years: C&Z Company's Custom Wholesale 9-12 Year Old Girls Training Bra & Underwear Set

For 9-12-year-old girls entering puberty, underwear that balances safety, comfort, and youthful charm plays a vital role in their development. As a specialized children's lingerie manufacturer, C&Z presents the Customizable Cotton Girls Underwear & Training Bra Collection, offering professional-grade solutions for brands, buyers, and parents with skin-friendly fabrics, ergonomic design, and playful details.

1. Targeted Design for Puberty: Smooth Transition from Childhood to Adolescence

Designed for the early development stage, the training bra features a wire-free soft support structure that gently lifts without restricting growth. The cup is made of 100% combed cotton with removable breathable padding, providing both support and airflow to reduce exercise-induced friction. The matching boyshorts use high-waist seamless tailoring with elastic waistbands and A-class cotton (tested safe for infants), passing strict national standards for formaldehyde and colorfastness—ideal for sensitive skin.

2. Customization Options: Functionality Meets Aesthetics

• Fabric Selection：Choose from pure cotton, cotton-spandex blends, and other skin-friendly materials for different seasons;
• Design Development：Customize cartoon prints, pastel colors, princess lace trims, or minimalist solids for school uniforms;
• Size Range：Covers 120cm-160cm heights with special AA/A cup sizes for early developers, solving the "too childish or too adult" sizing gap.
  Low MOQ (200 sets) makes it easy for brands, schools, or institutions to create exclusive lingerie lines.

3. Uncompromising Quality for Safety

1. Material Safety：All cotton fabrics are OEKO-TEX® 100 certified, free from harmful chemicals like fluorescent agents;
2. Skin-Friendly Details：Seamless stitching and rounded needle tips prevent irritation, with heat-transferred labels replacing scratchy tags;
3. Durability Testing：Passes 50-wash colorfastness and 2000-stretch resilience tests to ensure long-lasting shape and color.
