Are you talking about the ensemble? Or Garnet borrowing Roland's despair ID to shoot the maestro?
Argalia and the rest were also using suits made out of thread, which was Nuevo fabric, and Argalia's own clothes are specifically made to negate the damage the bullets cause, due to the vibration emitted by his gear most likely.

The Maestro is the highest ranked member of the ring that we know of, so obviously his clothes aren't just cheap fabric, but high quality shit that protects him too.
