SIR the Label Pants: Every Style, Fabric and Fit Note

SIR the Label makes pants in four families: fluid silk pants, relaxed cotton drawstring pants, wide leg tailoring and organic cotton denim. Almost every style fits true to size, and SIR’s own 0 to 4 sizing converts directly to UK 6 to 14. The newest is the Sorrento Bias Cut Pant in Black, a bias cut silk satin pant from Fall 2026. Here is every SIR the Label pant currently at SIR the Label at Coveti, grouped by family, with the facts that matter for fit.
