What makes a great “under‑blazer” white tee
Clean neckline that frames the face and sits smoothly under lapels crew or a refined V‑neck depending on jacket and occasion.
Mid‑weight, soft‑touch cotton for opacity and structure that won’t cling or show through under tailored weaves.
Slim, modern block for crisp lines across chest and shoulders; easy layering under blazers without bunching.
Crafted in England with meticulous finishing for a polished look from desk to dinner.
Limited capsule collections for elevated staples with a distinct, design‑led identity.
Plain White V‑Neck: Flattering neckline that sits neatly under tailored lapels; effortless day‑to‑evening transition.
Cotton Crew Neck: The classic under‑blazer staple breathable, soft‑touch, and made in the UK for a refined base layer.
Signature V‑neck Styles with Lapel Details: Mid‑weight cotton, back notch lapel, angled vents, and precise top‑stitching purposeful design that dresses up cleanly under a jacket.
Fit guidance for jacket pairing
Choose a slim or tailored cut to keep the chest and shoulder line sharp inside structured blazers.
For notch or peak lapels, a refined V‑neck elongates the neckline; for narrow lapels or minimalist tailoring, a clean crew is timeless.
Aim for a hem that meets or slightly exceeds the blazer’s opening to prevent ride‑up when moving or seated.
Fabric and construction details that matter
Mid‑weight cotton delivers the right balance of drape and opacity smart under worsted, hopsack, or textured blazers.
Collar and sleeve openings hold shape after wear, keeping a crisp edge at the lapel line and cuff break.
W.Rubens emphasizes quiet luxury through BCI‑aligned cotton sourcing and local, small‑atelier production in London.
Business‑casual: Crisp crew neck + navy blazer + tailored chinos clean, confident, and presentation‑ready.
Elevated evening: Refined V‑neck + black blazer + dark denim sharp neckline complements lapels for a lean silhouette.
Layered texture: Under an unstructured blazer or overshirt for depth without bulk; the tee anchors the look with minimalist precision.
The W.Rubens difference
W.Rubens turns the everyday white tee into a tailored essential for blazers: British craftsmanship, mid‑weight cotton, and minimalist, design‑led cuts released in limited capsules for enduring, quiet luxury under tailoring.
