A refined long-sleeve dress shirt built to be the most reliable piece in your rotation. Woven from soft, breathable cotton poplin with a quiet natural sheen, it stays crisp under a jacket and comfortable through a full day, from morning meetings to dinner. Tailored clean through the body for a sharp, modern line without feeling restrictive, it works buttoned to the collar with a tie or open with the sleeves rolled back.

Fabric and feel

  • Smooth, breathable cotton poplin with a subtle sheen
  • Lightweight and comfortable for all-day wear
  • Holds a crisp finish and resists creasing as the day goes on

Cut and construction

  • Tailored fit, clean through the chest and waist with room to move
  • Semi-spread collar that keeps its shape with or without a tie
  • Adjustable buttoned cuffs for a precise fit at the wrist
  • Reinforced seams with clean, even stitching throughout
  • Mother-of-pearl-style buttons, securely set
  • Removable collar stays to keep the collar sharp

Three colors, three moods

  • White: the timeless one. Formal events, the office, or under a suit, it never misses.
  • Blue: the everyday workhorse. Soft and versatile, easy with chinos, denim, or a blazer.
  • Red: the statement. A rich, confident tone for when you want the shirt to do the talking.

Styling Dress it up with tailored trousers and a jacket, or down with denim and clean sneakers. A true wardrobe staple that carries from desk to dinner without a change of clothes.

Fit and care

  • True to size with a tailored cut. Between sizes? Size up for a more relaxed feel.
  • Machine washable. Wash cold, hang or lay flat to dry, and give it a light press for a sharp finish.

Got two Valbruno shirts (brown and light blue), the linen is not as scratchy as other brands and fit well. Overall the service was great.

Came within a week, size was running on the smaller side so contacted support. They were quick to resolve with a free exchange.

I'm really pleased with these shoes from Atelier Sebastian. They arrived within six days and felt comfortable from the first time I wore them. The orthopedic support is excellent and has made a noticeable difference to how supported my feet feel throughout the day. They also look stylish, which can be hard to find with supportive footwear, so I would definitely recommend them.
