Gentle Support for Growing Girls: C&Z's 12+ Years Summer Cotton Development Vest Bra

As girls over 12 enter puberty, a comfortable yet protective training bra becomes a parent’s trusted choice. C&Z Company presents the Summer Thin Cotton Girls' Development Vest, combining Class A cotton fabric, wire-free design, and breathable tailoring to offer "zero-restriction growth companionship" for pre-teen and teenage girls, redefining comfort standards for adolescent intimate wear.

1. Class A Cotton Fabric: Cloud-Like Softness for Delicate Skin

Made from 100% combed cotton (infant-grade safety standard), the fabric undergoes bio-enzyme softening to a mere 0.2mm thickness (60% of regular styles), feeling as light as a cicada’s wing. Natural cotton’s moisture-wicking ability (2800mm/H₂O breathability) outperforms synthetic materials, keeping the chest dry even after 3 hours of wear in summer, preventing heat-induced skin sensitivity. OEKO-TEX® 100 certified, it contains no formaldehyde, fluorescent agents, or aromatic amines, with zero skin irritation in friction tests—safe for all-day wear by sensitive-skinned teens.

2. Puberty-Friendly Design: Gentle Support Without Underwires

• Micro-Elastic Chest Layer: Removable 0.3cm ultra-thin cotton pads with honeycomb ventilation provide basic coverage and support without compressing natural breast development, ideal for early stages (A cup and below);
• Seamless Tailoring: 2cm wide shoulder straps distribute pressure to avoid digging, while a 3cm elastic hem stretches with breathing, staying in place during running or skipping;
• Youthful Details: Lace trim or small bows on neckline/cuffs (20+ simple patterns) soften the "underwear" feel, helping girls build positive body awareness.

3. Summer-Specific Advantages: Lightweight Breathability for Hot Days

• Mesh Lining: 1mm breathable mesh on the back with 100+ air holes per cm² accelerates heat dissipation;
• Cropped Fit: Waist-length design stays hidden under school uniforms, avoiding awkward exposure;
• Quick-Dry Tech: Pre-shrunk fabric (≤3% shrinkage) dries naturally in 30 minutes, meeting frequent summer washing needs.

4. Wholesale & Customization: Supporting More Girls' Growth

• Inclusive Sizing: S (120-130cm), M (130-140cm), L (140-150cm), XL (150-160cm), with 1cm wider hem for 14+ girls to adapt to rapid growth;
• Custom Options: School logo embroidery, cartoon pattern customization (e.g., anime IP collaborations) from 100pcs MOQ, suitable for school purchases or brand labeling;
• Compliance: GB 31701 certification with 18 tests (formaldehyde, pH, sweat resistance), plus CE/CPC reports for cross-border sales, meeting global market standards.
