Style UW6928 coated, sprung-steel underwires are specialist full-bust wires designed for extreme size progression and volume accommodation.

This style features scaling from Size 6 to Size 30, with significant shape transformation across the range. The wire evolves from balanced moderate depth to deep, projected profiles with increasing seam-side asymmetry to provide enhanced support for larger cup sizes.

Available in European underband sizes 700-712, UW6928 systematically adapts to increasing breast volume through progressive depth increases and specialized asymmetry scaling for full-bust applications. Ideal for custom and couture uses.

Best for:

• Corset
• Full-coverage
• Specialist styles
• Support and structural styles

All Formline wires feature a unique nylon coating for the protection of wire casing and seams from wear and tear. Additional coating at each end of the wire provides a high level of comfort and minimises wire 'push-through'. To ensure high quality results we recommend Formline plush wire casing which is suitable for next-to-skin application.

Manufactured to a high standard; all wire sets are individually checked for quality, consistency and integrity.

See size guide for dimensions. For sampling, or prior to production, we recommend the purchase of a pair to test with garments and patterns.
