About Mr. Shitagi
The beginning
of Mr. Shitagi
Mr. Shitagi was born out of one simple but persistent frustration: undershirts that show through a dress shirt. Too thick. Too stiff. Poor fit, sweat stains under the armpits, and consequently uncomfortable by the end of the day.
Olivier, the brand’s founder, felt this had to change. He wanted an undershirt that not only fit well but felt as if it weren’t even there, invisible under your clothes, yet noticeably comfortable. No lines. No wrinkles. No sweat stains.
What followed was the development of the ultimate undershirt for every man, whether he has light or dark skin. Made from the finest fabrics, with a thoughtful design, and handcrafted in Portugal. That’s how Mr. Shitagi was born: the perfect base layer for men who know that style starts with the basics.
The name says it all
The name “Mr. Shitagi” wasn’t chosen at random. Shitagi is the Japanese word for undershirt, the first layer samurai would put on before donning their battle attire.
Not as an afterthought, but as an essential part of their preparation. A symbol of focus, precision, and respect for the ritual of dressing.
That same dedication is at the heart of our brand. At Mr. Shitagi, it’s all about the details: the fabric, the cut, the colors, the stitching. Every element is carefully considered, tested, and perfected, with one goal in mind: invisible comfort.
What sets Mr. Shitagi apart
Organic cotton
We deliberately choose organic cotton, soft on your skin, soft on the planet. Every fibre contributes to the comfort you feel all day long.
Elastane
A small detail with a big effect. Thanks to 10% elastane, the shirt moves with you, without pulling or pinching.
Antibacterial underarm zone
Not visible, but always there. This zone protects against odour, moisture, and discomfort, so you don't have to think about it.
Made in Portugal
Handmade, with genuine craftsmanship and quality.
