in your humor tour 2023 Main Logo T-shirt

¥3,600
Color: white
Material: 100% Cotton

I wrote about this on Twitter too, but this was designed by a younger guy who used to come to every single one of our live shows back in the "逃した魚" days. A lot of people said, "Cherish your connections," but it's not quite that simple. He won with this amazing design. He chose it from among many other candidates, without any忖度 (consideration for others' feelings). That's why it's even better. So we kept it simple, with the main logo, in an easy-to-wear material and design. < Iyori Shimizu >

In Your Humor Tour 2023 T-shirt.
The tour T-shirt, featuring a graphic that exaggerates the lighting imagery of the live performance, is now complete.
This piece features an impressive color scheme that looks great on both white and black bodies.

Colorful fluffy back number T-shirt

¥3,600
Material: 100% Cotton

We were talking about how we all wanted a T-shirt with "back number" on the chest. So we took just the letters from the tour's main logo, made them colorful and fluffy, and it turned out super cute, so we made it in black only. It's so cute, maybe we should have made a white one too. < Iyori Shimizu >

This is another tour T-shirt, featuring a different interpretation of the graphics compared to the "in your humor tour 2023" T-shirt.
By combining different processing techniques to match the design, the finished product offers a variety of textures and a delightful uneven surface.

White photo T-shirt水平線

¥3,600
Material: 100% Cotton

I decided to take a photo with the image of水平線in mind, so I opened a map and wondered where to go. After thinking and thinking, I suddenly decided on Shinjuku. I wasn't consciously thinking about it while I was taking the picture, but when I developed it, it looked like something by my favorite photographer, Saul Leiter, and it was wonderful. Whether it's music or photography, when you do it with a clear mind, you return to your childlike innocence and the longings that lie dormant within you come to the surface. < Iyori Shimizu >

This T-shirt features a photo print taken by Iyori for this design.
From reproducing the texture of a film camera to the printing method, this is a meticulously crafted piece, carefully chosen to reflect the image of the song.

ゴールデンアワー Black Photo T-Shirt

¥3,600
Material: 100% Cotton

The song has a strong theme of trains and buses, and the photoshoot involved walking a short distance from those stations and bus stops. I wanted to make back number logo in the middle more flashy, but when I tried it it looked too much like a typical "gal" style, so I went with a slightly more matte look. I liked that look too, but this one is easier to wear, right? < Iyori Shimizu >

A T-shirt featuring a photo print of an everyday scene captured by Iyori using a film camera.
This garment was inspired by the song "ゴールデンアワー".

Singing Hippo T-shirt

¥3,600
Material: 100% Cotton

I started drawing for no particular reason and it turned into a hippo. Hmm? Do hippos have horns? Oh well. It's powerful, but it's not shouting. It's singing.ベルベットの詩is also about a slightly controlled energy called "singing," not the scattered energy called "shouting," so I felt a sense of kinship with it. With the picture I drew. It's not someone else. With the picture I drew. It's not stupid, it's a hippo. < Iyori Shimizu >

This striking piece features Iyori drawn illustration rendered in gold silk screen printing.
We also paid close attention to the muted mocha body color.

アイラブユー Oversized Custom Pocket T-Shirt

¥4,500
Material: 100% Cotton

That's not it! It's not based on the concept of "always carry花束in your heart" at all! It's not that clever! It's simply a T-shirt with the lower half of the colorful brain character "Brain Boy" hidden in the pocket! Oh! And it's a little bit thicker than the others! < Iyori Shimizu >

This long-sleeved T-shirt has a great color and the design fits perfectly, making it a very clear and themed piece.

¥4,800
Material: 100% Cotton

HUMOR Zip-Up Hoodie

¥8,500
Material: 100% Cotton

I had already drawn up the design idea for this "AN" and "OR" in my notebook during the SCENT OF HUMOR TOUR. I really like it because it feels like it represents the album and its theme.
The back is made of a different material, and the straps are thick; it's simple, but actually has a lot of thought put into it. It would look great even if you changed the straps to something you like. < Iyori Shimizu >

Iyori-Painted Member Towel 2023

¥2,000
Material: 100% Cotton
Size: 85cm x 34cm

A super close-up of the members. Definitely not something you'd want as a souvenir. Maybe for people who've "heard of us before but don't really know us," the logo towel would be better? I wonder. Hey, what am I even talking about here? < Iyori Shimizu >

The three members, Iyori Iori, are finally appearing on face towels.
The three figures, depicted in a bold print that spills out of the towel, are both humorous and incredibly eye-catching.

In your humorous graphic towel

¥2,000
Material: 100% Cotton
Size: 85cm x 34cm

Some of you may have noticed, but these kinds of things are the hardest to color scheme. There are an endless number of options. And when I think about it, I often end up settling on cool colors like blue. But the album is黄色based, so this time I consciously tried to make warm colors stand out, but wait, if you look closely, the contents are actually all blue and green. Hmm. It's all about balance, isn't it! < Iyori Shimizu >

Another tour towel, designed from a different angle than the "in your humor tour 2023 face towel."
We've incorporated a pop design reminiscent of the new retro Y2K era.

I think the way the hands are growing out is exquisite and it turned out really well! < Iyori Shimizu >
