Questions, answered

Everything you need to know before choosing your next suit.

Avoid sizing guesswork with our Complimentary Fit Assistance. Use our Online Suit Size Calculator or reach out to our tailoring team at cyriel@kossateliersuits.com before ordering.

A well-fitting suit should feel comfortable through the shoulders, sit cleanly at the chest, and drape without pulling. Using our Suit Size Calculator accurately before ordering is the best way to get this right on the first try.

Use our Suit Size Calculator and compare the measurements with a suit you already own that fits you well. If you're between sizes or unsure, contact us at cyriel@kossateliersuits.com before ordering.

Email us at cyriel@kossateliersuits.com with your order number, photos, and your originally submitted measurements. If the garment doesn't match what you submitted, we'll cover the full cost of correction or send a replacement. If the issue traces back to submitted measurements, you're covered by our one-time $75 fit credit.
