Coldseam is less a manufacturer than a network of Shelf tailors and menders operating out of converted storage units near the lower Meridian drainage corridors. Their formal separates are assembled from bolt-end fabric lots, surplus corporate uniform material (Ouroboros gray appears often), and whatever structured textile can be sourced at the district swap markets. The shirt is banded-collar, pressed stiff with a starch substitute made from processed grain byproduct. The trousers have a clean line through the thigh that collapses into a patch at the left knee, covered with a fabric square that almost matches.

For Φ14, this is a complete formal outfit. It fits because a Coldseam tailor measured you or someone close to your size. The tailors who run these networks have memorized body types the way doctors memorize symptoms — practically, without ceremony. Some of their customers are augmented with basic chrome, and the shirt cuffs are cut slightly wider on request to clear a forearm data-port without snagging.
