Part shirt, part light jacket, all useful. A midweight cotton overshirt built to layer over a tee, the dress shirt, or the crewneck. Wear it open as a jacket or buttoned as a shirt, the transitional piece that does the most work in your wardrobe for half the year.

Fabric and feel

  • Midweight cotton with a clean structure, soft but substantial
  • Holds its shape and drapes well, heavier than a dress shirt for a real layering feel
  • Breathable enough for spring and fall, warm enough as a light jacket

Cut and construction

  • Relaxed, modern fit cut to layer cleanly over a tee, shirt, or sweater
  • Shirt-style collar that sits sharp open or closed
  • Full button front with subtle tonal buttons
  • Two chest patch pockets, clean and functional
  • Buttoned cuffs and reinforced seams throughout

Three colors, three moods

  • Navy, white and tan.

Styling Open over a white tee and denim for off-duty, or buttoned over the crewneck with tailored trousers for something more put-together. The layer you keep on all day.

Fit and care

  • Relaxed layering fit, true to size. Want it roomier over thick knits? Size up.
  • Machine washable. Wash cold, hang to dry, light press if needed.

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.
