Custom Contrast Strap Sports Bra - High Elasticity, Square Neck Yoga Crop Top
Bloomto's custom contrast strap sports bra combines a modern square neck, wide contrast-color straps and a high-elasticity cropped body for yoga, pilates, barre and streetwear layering. The knit delivers a measured elastic recovery of ≥ 95% and wicks moisture in ≤ 3 seconds, keeping every downward dog and sun salutation dry and supported. Fully customizable colorways, logos and size runs make this style a clean canvas for your brand.
Why Our Custom Contrast Strap Sports Bra Outperforms
Each card follows the FAB principle - a real Feature, a measurable Advantage and a tangible Benefit for your customers and your brand.
Wide Contrast-Color Shoulder Straps
Feature: 3.2 cm wide shoulder straps with contrast-color binding, double-needle coverstitched to the front and back panels.
Advantage: Load is distributed across 38% more shoulder surface than standard 1.5 cm straps, with a seam strength of ≥ 200 N (ISO 13935-2) on every stress point.
Benefit: No dig-in, no slip-down - wearers stay focused on their practice instead of adjusting their top, the number one complaint on competing sports bras.
Strap seam strength ≥ 200 N | Shoulder load distribution +38% | Shape retention 50+ wash cycles
Square Neckline with Anti-Roll Edge
Feature: Clean square neck framed by a flat 12 mm contrast binding tape, stabilized by a 2.5 cm coverstitched inner stay.
Advantage: The neckline keeps its geometry after 50+ machine wash cycles with no edge curling, verified by stretch-recovery tests on the finished garment.
Benefit: A flattering modern silhouette that reads premium on the shelf and stays premium after months of wear, lifting your brand's perceived quality and cutting return rates.
Wash durability 50+ cycles | Edge curl 0 mm | Color fastness to washing Grade 4-5 (ISO 105-C06)
High-Elasticity Moisture-Wicking Knit
Feature: 75% nylon / 25% spandex interlock knit at 200 GSM with 4-way stretch and a moisture-wicking finish.
Advantage: Fabric elastic recovery rate ≥ 95% after 50 stretch cycles (ASTM D3107), vertical wicking ≤ 3 seconds (AATCC 197) and drying time ≤ 30 minutes keep skin dry during hot flows.
Benefit: Move freely from chaturanga to coffee without the bra riding up, sagging or turning transparent - the comfort drivers that earn 5-star reviews and repeat orders.
Elastic recovery ≥ 95% (ASTM D3107) | Wicking ≤ 3 s (AATCC 197) | Drying ≤ 30 min | UPF 50+ | pH 4.5-7.5
Removable Padded Cups
Feature: Soft removable molded cups with a secure inner pocket opening and smooth interior seams.
Advantage: Wearers can add or remove support in seconds; fabric and cups are OEKO-TEX Standard 100 and REACH compliant for skin-safe contact.
Benefit: One SKU serves different support needs and preferences, reducing fit-related returns and widening your target market from yoga newbies to seasoned practitioners.
OEKO-TEX Standard 100 certified | REACH compliant | Formaldehyde N.D. (ISO 14184-1) | Pilling ≥ Grade 4-5 (ISO 12945-2)
