1. Let's make our time at home even more fulfilling.

With people spending more time at home due to "STAY HOME," many have likely had a good opportunity to reconsider what to wear when relaxing in the living room or dining room, realizing that "you can't really spend the whole day in your pajamas." When choosing loungewear to wear with family, the key is to strike a balance between a neat appearance and relaxed comfort. Furthermore, when working remotely, items made from high-quality materials that convey a soft atmosphere without looking too formal are particularly effective.

Making a good impression through remote work


Its ease of use, allowing you to quickly throw it on for impromptu web meetings, is its main appeal.

  • <DETOIRE> Knit jackets : ¥16,500 each
    (100% cotton/M/L)
    View Products

For business meetings and important conferences where you want to maintain a professional appearance even on screen, a knit jacket is recommended as it combines comfort and a clean look. The key advantage of a knit jacket is that it doesn't look too casual even when worn with a T-shirt or polo shirt underneath. Its slim silhouette creates a neat look, making it convenient for casual outings as well.


When viewed on a monitor, a knit polo shirt gives a softer impression than a pique knit.

This dressy knit polo shirt is a versatile item that can be worn on its own or as an inner layer under a jacket. This Mitsukoshi Isetan exclusive knit polo shirt, featuring a silhouette adapted from the popular knitwear brand BATONER , is a recommended choice in any color for a sophisticated everyday look.

Supporting the increasingly important "relaxation and refreshing feeling"


The calming colors and design make you feel relaxed both mentally and physically just by changing into them.

The state of emergency declared on April 7th (Tuesday) has drastically changed the business world. Many people have likely realized the importance of face-to-face meetings after experiencing web conferences and other forms of self-isolation. As restrictions are gradually lifted, it's important to be more conscious of what you wear and to make a good impression when interacting with others. Let's enjoy smart cool business attire.

Prepare for the rainy season starting from your feet. A pair of shoes that will boost the motivation of businessmen.

The comfort you feel while wearing it is truly remarkable.
