Factory Quick Specs
Product Description
Wholesale Premium Girls Training Bras S902 (Strap Bra / Developmental Underwear for Tweens) is the first cup-sized training bra designed for tween and early-teen girls (heights 140–170 cm) who need a real-cup silhouette with proper shoulder straps. The main body is 95% combed cotton / 5% spandex, a premium natural-fiber blend with gentle four-way stretch and shape recovery. The combed cotton construction uses longer-staple cotton fibers (comb treatment removes impurities and aligns fibers) for a softer hand-feel against developing skin than standard carded cotton.
The cup-sized fit (75A / 80A / 85A) is the right first-bra progression for girls aged 11–15 entering puberty. The A-cup designation reflects the standard B2B cup-size convention for developmental bras — the “A” indicates the cup volume (smallest conventional cup), and the leading number (75 / 80 / 85) reflects the underbust measurement in centimeters. Sized in three real cup sizes (rather than age-based S/M/L/XL), S902 lets buyers and tween customers select the right cup fit for the developing body.
The strap-bra silhouette pairs a structured cup body with adjustable shoulder straps and a hook-and-eye back closure — a step-up from the seamless wireless cami (H training bra) and the seamless nylon triangle mid-rise underwear (S2942). S902 is positioned as the premium cup-sized training bra in the developmental-underwear line, paired with S913 (Premium Camisole / BX377) which uses the same 95% combed cotton / 5% spandex fabric in a tank-top silhouette. Custom color development, woven labels, heat-transfer logo and branded retail-ready polybag are available for OEM partners.

Product Overview
For Tweens
The cup-sized fit (75A / 80A / 85A) is the right first-bra progression for girls aged 11–15. The 95% combed cotton / 5% spandex fabric is soft, breathable and supportive without bulk. The adjustable shoulder straps and hook-and-eye back closure let the bra grow with the developing body.
For Parents
Combed cotton is naturally hypoallergenic and softer than standard carded cotton — gentle on young developing skin. The structured cup-and-strap silhouette is the right next step after a seamless wireless cami (H training bra) and a seamless triangle underwear (S2942). From 2 pcs on selected in-stock styles, colors and sizes per size & color for accessible boutique and DTC launches.

Size Chart (Strap Bra S902 / BX376 per Spec Sheet)
S902 is sized in real bra cup sizes (75A / 80A / 85A) covering girls aged 11–15 (heights 140–170 cm). Garment measurements are flat-laid in centimeters.
Measurement Note (per spec sheet): All measurements are flat-laid in CM. Chest measurement is the full cup-band width; Side Length is the cup-to-strap join length; Middle Length is the cup center-front length. The leading number in the size code (75 / 80 / 85) reflects the underbust measurement in centimeters, and the “A” reflects the cup volume. There is approximately a 1-2 cm tolerance range due to individual measurement habits.

Frequently Asked Questions
What is the fabric composition of this girls training bra?
S902 is made from 95% combed cotton / 5% spandex, a premium natural-fiber blend with gentle four-way stretch and shape recovery. Combed cotton uses longer-staple cotton fibers (comb treatment removes impurities and aligns fibers) for a softer hand-feel against developing skin than standard carded cotton. The 5% spandex gives the bra gentle stretch to grow with the developing body.
What sizes and cup sizes does S902 cover?
Three real cup sizes: 75A (heights 140–150 cm), 80A (heights 150–160 cm), 85A (heights 160–170 cm). The leading number (75 / 80 / 85) reflects the underbust measurement in centimeters, and the “A” indicates the cup volume (smallest conventional cup). For the developmental tween bra market (ages 11–15), real cup-sized fit is the right progression from the seamless wireless cami (H training bra) and the seamless triangle underwear (S2942).
What does “A cup” mean in this training bra context?
The “A” in 75A / 80A / 85A is the standard B2B cup-size designation for the smallest conventional cup volume. The leading number (75 / 80 / 85) is the underbust measurement in centimeters. This is the right first-bra cup size for early-puberty tweens; as the developing body grows, customers step up to the next cup volume (B, C, etc.) and the next band size. For tween bra programs targeting ages 11–15, A-cup is the standard entry point.
Is S902 OEKO-TEX Standard 100 listed?
OEKO-TEX Standard 100 application is currently in progress (not yet issued). In the interim, S902 is tested against GB 31701 Class A (China infant and children textile safety, the strictest tier covering formaldehyde, pH, odor and AZO amines), is documented for CPC (Children’s Product Certificate, US market — CPSC Lab 1693), and can be third-party inspected by TÜV SÜD / SGS / Intertek on a per-shipment basis. All dyes and materials meet eco-friendly standards during production.
What is the MOQ, lead time and sample policy?
Ready stock: From 2 pcs on selected in-stock styles, colors and sizes, ready-to-ship within 48 hours from confirmed payment. Custom OEM: MOQ quoted per colour or artwork — stock-fabric programs with from 2 pcs on selected in-stock styles, colors and sizes; fully custom dyed fabric: MOQ is confirmed after reviewing fabric composition, GSM, yarn count, size range, artwork, print method, construction and other customization requirements. Lead time ~25 days from artwork sign-off for new colours and ~45-55 days for fully custom dyed fabric. Samples: sample yardage (a finished stock piece + spec sheet) is available at nominal cost, refunded against the bulk order; full custom prototype samples take ~10-15 days and incur a small lab-dip fee.
Do you support OEM / private label and custom artwork?
Yes. We support OEM, ODM and private label. Custom color development on the combed cotton base, woven labels, heat-transfer logo, custom care tags and branded retail-ready polybag are all available. For exclusive character IP artwork on the cup or band, an NDA and a per-design fee may apply — share your target character / IP timeline and we will confirm feasibility.
What compliance documentation do you provide?
For every shipment we provide: commercial invoice and packing list; Certificate of Origin (Form A / E / F per destination); GB 31701 Class A test report per fabric batch; CPC documentation (Children’s Product Certificate) for the US market (third-party lab 1693); AZO-Free test report; care label compliance; and on request third-party inspection reports from TÜV SÜD, SGS or Intertek before shipment.
How does S902 compare to your other developmental bras?
S902 is the premium cup-sized strap bra in our developmental-underwear line. We offer a three-tier developmental bra progression for tween and early-teen girls: (1) S2942 Seamless Triangle Mid-Rise Underwear (Nylon / Spandex, age 11–15, no-show seamless) — the entry innerwear layer; (2) H training bra Seamless Wireless Camisole (Rayon / Spandex, age 11–15, seamless wireless cami) — the first wireless layer; (3) S902 Premium Strap Bra (95% Combed Cotton / 5% Spandex, age 11–15, real cup 75A / 80A / 85A, structured strap-and-closure) — the first cup-sized structured layer. Plus the S913 Premium Camisole (same fabric as S902, tank-top silhouette) for buyers who want both strap and cami styles.
What is the care routine for a cup-sized developmental bra?
Per spec sheet: machine wash cold at 30°C / 86°F or below; hand-wash recommended for cup-shaped structured bras to preserve the cup shape over time; do not bleach; air-dry flat (rather than tumble dry) to preserve the cup structure. Avoid wringing the cups; reshape while damp. These care notes can be applied as a standard heat-transfer care label on the inside back band for OEM partners.
What is the difference between S902 (strap bra) and S913 (camisole)?
Both use the same 95% combed cotton / 5% spandex fabric and the same three cup sizes (75A / 80A / 85A). The difference is the silhouette: S902 (BX376) is a strap bra with adjustable shoulder straps and hook-and-eye back closure — the right next step for tweens who have outgrown the seamless wireless cami; S913 (BX377) is a camisole / tank-top silhouette with built-in cups but no straps or hook-and-eye closure — the right first-bra entry for early-puberty tweens who prefer a softer structure. Both can be stocked together for a complete developmental bra line.
