Easy and modern is justice. The deep appeal of tracksuits based on adidas Sportswear's TIRO.

H: This is a "suit-up" model set-up. What is the difference between this and the tracksuit you mentioned earlier?

Izumi: If you look closely, you can see the overall pattern, so I think fashion lovers will enjoy this set-up more in town. The pattern and the body are of the same color, so even though it is an all-over pattern, it is not obnoxious.

H: Are you also particular about the size of these, and do you let the models wear them?

Izumi: I tried not to make them wear too big. I thought it would be cooler to wear it just the right size, in line with the shoulder position.

H: This outfit is typical of Izumi's style as a soccer fan.

Izumi: The styling was inspired by people heading to futsal or soccer fields. The motif of the hair band wrapped around the head is that of an overseas soccer player.

H: It feels fresh to wear a hair band in the city.

Izumi: I don't know if you are familiar with hair bands in Japan, but many people in London wear them as a fashion item.

H: What do you wear with your innerwear?

Izumi: This is an Adidas game shirt from the 1980s.

H: Did you choose orange to bring in the color?

Izumi: Yes, that's right. I think sports-style items go well with colorful items. Game shirts made of slippery material match the fabric of tracksuits, so even loud colors blend in.

H: Color makes me feel good, doesn't it? Is that your intention with the yellow socks?

Izumi: Yes. I change into soccer socks while playing soccer, so I wear them only for transportation or to make them look like street clothes.

H: The last style is with a tailored jacket.

Izumi: This style is inspired by the jacket and track pants style often seen in luxury brand collaborations. The inner layer is a sporty yet traditional looking rugger shirt, which brings it all together in a classy way.

H: Sports-style pants are easy to blend with elegant tops.

Izumi: If the bottoms are beautiful tapered pants, the tops should be classy, not old-fashioned or otherwise unfashionable, to bring it all together nicely.

H: What is the significance of the headphones together?

Izumi: I wanted to add an element of club culture to the dressed-up jacket style, so I put headphones around my neck. Also, the model himself is a dancer, so I thought headphones would be a good accessory. He danced in the promotional movie.

H: So that was your aim. Changing the subject, is there any reason why you let a tightly made item like this "suit-up" fit true to size?

Izumi: It's because the silhouette would be broken. If something was originally designed with tight sizing, it would look cooler if worn just right.

H: Why is that?

Izumi: I respect the creator, or rather, I don't think it is necessary to choose oversized items that were made to be worn tight. Rather than breaking it down by size, this type of item should be broken down by the way it is matched, which will bring out its originality.

H: In the past few years, I have noticed more and more people wearing track jackets and pants in the city. What do you think are the reasons for this?

Izumi: I think it is because there have been more collaborations between sports and luxury brands. There have been more style proposals using track jackets, so I think the influence of these collaborations has made it easier to incorporate track jackets into fashion. Besides, there are a lot of sportswear in thrift stores.

H: Indeed, I am seeing more and more tracksuits from the 2000s in thrift stores.

Izumi: Another thing that I am personally into these days is to match such sporty items with authentic workwear. When I do this, I end up dressing like the hooligans who were in the area at the time. They would wear cheap work pants and track jackets to the stadium, just like work clothes. But if you were to wear such a style in Japan, you might look suspicious, so it would be better to wear basic chinos or denim (laughs).
