"I was chasing functional beauty, and it ended up being stylish"—5 clothing and innerwear items seriously selected by an engineer VTuber

Hello, this is Nisena Hiro.

Recently, every time I update my Rakuten Room, I've been getting questions like, "Why did you choose this?" I'll be honest. My shopping criteria is Functionality:Appearance = 7:3. The habits of someone who has spent 10 years in the field of electronic components and communication infrastructure have thoroughly seeped into my clothing choices (laughs).

This time, I will dig deep from an engineer's perspective into 5 items from those I introduced on Rakuten Room that I am truly glad I bought.

1. Pettipants—The aesthetics of "invisible design"

When wearing a dress, the transparency of the hem or static electricity can gradually become a concern, right? That's where these pettipants come in.

In the world of electronic components, they are like cable organizers that tidy up wiring. They aren't visible from the outside, but they raise the overall quality by a notch. They ensure a comfortable fit with an elastic waistband and even include anti-static functionality. At ¥2,699, the perfection of this design honestly makes me worry, "Are they making a profit on this?" (laughs).

At first, I thought, "¥2,699 for innerwear..." But when I actually used them, the silhouette changed completely. The design of the invisible parts determines the perfection of the whole—it was the exact same rule for electronic components and clothing. When I realized this, I felt a bit frustrated. I wished I had noticed it sooner.

2. Non-iron blouse—Success in "optimizing morning routines"

As an engineer, I find pleasure in cutting out inefficient processes that occur repeatedly.

"Ironing" has been a long-standing issue. Spending 5 to 10 minutes just to smooth out wrinkles during the precious morning hours. In software terms, it's like leaving a "known bug that requires a restart every time" unaddressed. This blouse is non-iron, machine-washable, and opaque—in other words, maintenance costs are almost zero. It maintains a neat silhouette while cutting out the daily hassle entirely.

The moment it arrived, I was a bit stunned, thinking, "This is ¥2,590...?" In a good way. The peace of mind of not having to worry about my "appearance" every time I go out or travel between streams is definitely reducing mental noise.

3. Made-in-Japan Dress T-shirt—I understood the "true nature" of the price difference on my skin

¥10,450. Someone who isn't familiar with fashion might think, "Over 10,000 yen for a T-shirt?"

But the moment I put on this dress T-shirt from RE MADE IN TOKYO JAPAN—I realized, "Ah, so this is the true nature of the price difference.".

The same thing happens in circuit board design. Cheap parts and high-quality parts that look "not much different" when you only look at the spec sheet. When you actually implement them, the noise resistance and aging characteristics are completely different. Clothing is the same; your body tells you the texture of the fabric and the precision of the sewing the "moment you put it on." It has a wide silhouette but doesn't look sloppy—calculated design functions exactly the same way, whether it's electronic components or clothing.

For those looking for "just the right amount of neatness" to switch from work to off-duty, this is one piece I can confidently recommend.

4. Double Gauze T-shirt—I was impressed by the design for "long-term comfort"

The enemies of long hours of desk work or streaming in the summer are heat, stuffiness, and a drop in concentration.

This T-shirt is made of 100% cotton with a double gauze structure. Double gauze creates a fine layer of air between the two layers of fabric, doesn't it? It's a structural design at the material level that achieves both sweat absorption and breathability. As an engineer, when I learned this, I was impressed, thinking, "So that's the idea, I see."

I've been doing this for 10 years, and I've always felt that optimizing my summer work environment never quite went well—but honestly, this T-shirt was a bit of a lifesaver. The lace sleeve detail adds a touch of elegance so it's not just a "big T-shirt," and the length, which covers down to the hips, is also logically designed. At ¥2,999, the level of perfection and value for money is just too good.

5. Relive Spats—The concept of "recovery efficiency" embodied in clothing

This is the product that impressed me the most from an engineering perspective among these five items.

When you're doing long hours of desk work or streaming, leg fatigue accumulates more than you'd think. At first, I was honestly skeptical, thinking, "Can innerwear really make that much of a difference?" But the moment I saw the term "indirect taping technology," I intuitively became interested, thinking, "This is a product designed with the body's structural design in mind."

When I actually tried them out, the heaviness and fatigue in my legs after a stream felt clearly different. ¥13,200 might seem expensive, but when you view it as an "investment in the hardware that is your body," I think it's actually on the cheaper side. After all, the final hardware that runs every process is your own body.

Summary—Beyond chasing invisible design

What these five items have in common is that "invisible ingenuity is embedded in the design."

The habit of deciphering the design philosophy of electronic components as an engineer has, before I knew it, been applied directly to choosing clothes. When you think about "why this material?" or "what is the meaning of this shape?," shopping becomes a slightly different way to enjoy yourself.

I also update items on Rakuten Room from time to time, so if you're interested, please take a look.
