A. Use cool materials and colors for fabrics and accessories.

This year marks the 10th anniversary of Cool Biz, and it has now become widely recognized, with a variety of outfits being proposed. You are probably choosing items with attention to detail, such as material, design, comfort, and functionality, aren't you? However, even in summer, you want to dress properly for formal occasions. This time, Otsubo from the Business Clothing department on the 5th floor Isetan Shinjuku Store, Men's Building will introduce three recommended Cool Biz styles that are cool in both appearance and comfort.


[Beginner Level] Classic suit style: Solid navy blue



[Intermediate Level] Choose a paisley pattern for a bright navy that's perfect for summer.


Next up is the intermediate level. This outfit features a more summery and refreshing color combination than the beginner level. The mohair-blend twill fabric is from the Italian company Drago, and its soft sheen and high-quality feel are key features. The style prioritizes lightness and softness in tailoring, so there is none of the "stuffiness" that suits often feel during this time of year. The brightly colored blue linen suit and the boldly placed paisley tie create a classic impression while also enhancing the light and refreshing feel.

[Advanced] A light gray suit with a sophisticated look can also be made with a windowpane pattern.


Finally, we have the advanced version. This suit uses 100% wool fabric from the Italian company Canonico. It features a highly breathable fabric compared to regular wool fabrics, thanks to the use of tightly twisted yarn. The finely textured fabric doesn't cling to the skin, and unlike the suit fabrics in the beginner version, it has a soft sheen and crisp texture, giving it a luxurious feel. The refreshing light gray with blue windowpane checks makes this suit stand out. Pair it with a seersucker tie for a thoroughly summery, advanced look.

All the shirts used in this collection are made from Majotae, a linen fabric revived in modern times using the latest Japanese spinning technology. It dries faster than cotton, feels refreshing against the skin in summer, and retains heat well, making it warm in winter and comfortable to wear all year round. Majotae custom-made shirts start from ¥37,800 (tax included).

Hemp fabric, which had been forgotten for over half a century, saw a drastic decline in domestic production after 1948. However, by using hemp that does not contain hallucinogenic substances, this fabric brand has revived it for the modern era using Japan's proud, cutting-edge spinning technology. *Majotae uses harmless hemp raw materials.


How was it? Even in the hot season, you can create a refreshing suit style with a little ingenuity. Bright navy, which we also introduced in the intermediate section, is particularly popular this year. It looks cooler than navy, and the synergistic effect of it being a trendy color is sure to give a good impression. Also, with the increasing trend towards casual styles within cool biz, it's easy to match with jacket and trouser styles, which is another plus. Let's make this year's cool biz style cooler, more comfortable, and more stylish.
