Where Tier 3 hides augmentation behind standard seams and Tier 5 renders it irrelevant through sheer tailoring, Tier 4 does something more interesting: it puts the chrome on display. The Nullweave aug-display formal suit is cut for the specialist who has earned their chrome and wants the boardroom to know it. The jacket is a slim double-breasted cut in Nullweave's signature light-absorbing matte black fabric — not true vantablack, but a deep structural dark that reads as a void against the office's fluorescent ambience. The left sleeve is constructed with a full open-channel system: a structured chrome-display cut that runs from shoulder to wrist, framing a mechanical arm or chrome forearm prosthetic with a border of matte black piping that makes the augmentation look intentional rather than accommodated. The right sleeve is standard. Trousers are the same matte black Nullweave fabric, slim through the thigh with a moderate break, and a single aug-channel seam along the outer right leg for a prosthetic limb or exo-brace. The shirt beneath is a Nullweave house poplin in deep charcoal — not white, a deliberate departure. A slim matte-black tie with a single diagonal line of micro-reflective thread. Footwear is Meridian Standard Chrome-Last boots in black, the chrome toe-cap polished to mirror finish — the only reflective surface in the ensemble, and clearly intentional. The BCI port at the temple is left uncovered, the port itself brushed steel.
