At sébastien, fit is not incidental — it is architectural.

Each piece of garment is constructed to offer:

• Sculpted, close-to-body support
• Controlled, intelligent stretch
• A seamless silhouette beneath tailoring
• Breathable precision in Tencel™ Lyocell

Our cuts are deliberate — refined, balanced, composed.
Never excessive. Never restrictive.
