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'. For high-quality outcomes, Formline plush wire casing is recommended for use with all wires.
Manufactured to a high high standard; all wire sets are individually checked for quality, consistency and integrity.
See size guide for dimensions. Please note that volumetric cup sizing is estimated only and wires may be applicable to a wider range of cup sizes than described. For sampling, or prior to production, we recommend the purchase of a pair to test with garments and patterns. For enquiries regarding bulk orders or expanded grading options please email us.
