Every piece is made from carefully selected materials. Please follow the care label inside the garment. As a rule of thumb: wash knitwear cold and dry it flat, and have tailored outerwear professionally dry cleaned to keep its shape for years.

Free US shipping on every order. Orders are processed within 2–4 business days, then delivered within 3–4 business days. You'll receive a tracking number by email as soon as your order ships.

90-day returns. Return unworn items in their original condition within 90 days of delivery. Email us and we'll send you a printable return label; the label cost is deducted from your refund, except for damaged, faulty or incorrect items. Full return policy
