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. 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.
