GUIDE crew members Tsuchiya and Tashiro visited "Keylime Tokyo" in Meguro Ward, Tokyo. It's a select shop run by fashion improver Seki.

This time, the theme of our "Adult Field Trip" is none other than "Adult Black." Based on lectures from crew members Tsuchiya and Tashirogaseki, we will experience the latest styling techniques that feature black as the main color.

"Black seems difficult to wear," "All-black outfits tend to look heavy"—we introduce sophisticated black styles that defy these stereotypes. Don't miss the unique item selection from " keylime Tokyo " and Seki's detailed styling explanations.

Tsuchiya: "Black denim expands your styling options, creating a more sophisticated adult style."

Tsuchiya is taking on the challenge of wearing " keylime Tokyo " original black denim. Although Tsuchiya has always loved jeans, this is her first time trying black denim. Seki will talk about its appeal and tips on how to wear it.

Seki: This is perfect for Tsuchiya-san, who's trying black denim for the first time. These jeans are slightly tapered, neither too wide nor too narrow, and have a relaxed waist with an inner drawstring. The "Keylime" green color is a key feature. The 12.5 oz fabric is lightweight and easy to wear in any season.


Tsuchiya: It's certainly lightweight, and the silhouette is beautiful. It looks like it would be useful in both summer and winter.

Seki: This denim has white weft threads, so as you wear it, it fades to a grayish color and doesn't become heavy. Furthermore, the twist in the fabric gives it a vintage feel, enhancing its character. It also doesn't stretch out at the knees easily, so you can wear it nicely for a long time.



Tsuchiya: When I actually wear them, they make me look more put-together than my usual casual style. They also seem to go well with striped shirts and jackets.

Seki-san: Actually, try pairing it with a black jacket. Blue tones give a fresh and clean look, but black instantly adds a touch of sophistication. The key is that it's not too stiff, but still gives off a sense of elevated style.

Tsuchiya: Oh, this would work for dates or even at restaurants.


"Just adding a pair of black denim jeans to your wardrobe dramatically expands your styling options. You can wear them casually or dressed up, with complete freedom. Above all, they're an item that really captures the 'current mood'," says Seki. Tsuchiya adds, "These would go well with a variety of tops like jackets, shirts, and T-shirts," looking forward to mixing and matching them in the future.

Tashiro: "Adding a twist to black style. Enjoying adult black with white pants."

Tashiro, who often wears black in her daily life, was introduced by Seki to "a style that makes the most of black while adding a fresh touch."

Seki: Tashiro-san is usually good at wearing black, so how about adding a twist this time and using black as the base color and combining it with white denim as an accent color?

Tashiro: That's true, I tend to stick to all black... But pairing it with white pants is a fresh idea. A black T-shirt and leather shoes with these white pants. It looks really clean and light.


Seki: These pants are a new color of Oblada's white denim, made with the same hemp blend. Because it's not pure white but more of an ivory shade and has a soft texture, it won't look stiff even when incorporated into a monochrome outfit. The white adds just the right amount of lightness to the strong black.

Tashiro: The heaviness of the black is subtly softened, making the whole outfit feel lighter. When I actually wear them, they feel incredibly light. They're comfortable and relaxing without feeling restrictive, and I like that the silhouette doesn't look sloppy.


Seki: Black is a very versatile color. When it tends to become monotonous, a little ingenuity, such as adding white, can drastically change the impression. The key to sophisticated black is balance and a playful touch.

On this day, Tashiro's outfit, which was based on an all-black style, evolved dramatically with the addition of white pants. Despite being monochrome, it didn't look heavy, and he was able to exude a sophisticated atmosphere. This "twist" technique of adding freshness to a black-based outfit is also recommended for adults who prefer a simple style.

Summary: Adult black is free and fun.

Through their learning experience at Keylime Tokyo, Tsuchiya and Tashiro seem to have had a significant change in their perception of "adult black." They can broaden their styling options with black denim, or play with accent colors and textures while keeping black as the base. "Adult black" is by no means a monotonous style, but rather a style full of freedom and enjoyment.

As Seki-san said, "The most important thing about fashion is to enjoy the 'now'," so please try creating your own unique "adult black" look.
