N. Hollywood, a designer brand that constantly innovates through its diverse lines and projects, is releasing a new "50" size in its top-of-the-line underwear line, N. Hollywood Under Summit Wear, which is a significant departure from its existing sizing. We spoke with Ryuji Kawasumi, N. Hollywood All Store Manager, about the reasons why N. Hollywood Under Summit Wear continues to receive such enthusiastic support from a wide range of people, the meaning behind this new size, and the importance of choosing the right size.

Let's take a look at the three models that will be released in size "50" this time.

Why N. Hollywood Under Summit Wear is Loved

Led by Daisuke Obana, N. Hollywood is a designer brand that Japan proudly presents to the world. While maintaining the brand's worldview, it develops diverse and varied creations, including the formal line N. Hollywood Compile and N. Hollywood Test Product Exchange Service, which draws design inspiration from military wear.

Among them, N. Hollywood Under Summit Wear (NHUSW) stands out as particularly unique, specializing in underwear and basic items. While fashion enthusiasts each have their own favorite brands and designers, N. Hollywood has gained widespread support from people of various generations and styles, and many people consider it their go-to brand for underwear.

Why do designer underwear lines attract so many people? We asked Ryuji Kawasumi, the all-store manager for N. Hollywood and a long-time user of N. Hollywood himself, for the reason.

"First of all, I think one of the key points is that, as a Japanese designer brand, they were quick to focus on underwear and develop it as a proper line. Underwear, which can be the main focus of an outfit, was also an item that symbolized the brand."


Underwear, once literally just lingerie hidden from public view, has evolved over time into visible underwear, and then into underwear designed to be alluring. NHUSW has established itself as a daily standard for underwear that is high-quality, comfortable, and elegantly stylish. Its beautiful patterns, high quality, versatility, and unique balance have attracted an astonishingly wide range of fans.

"Elegant basic items are not only great for creating a polished look, but they are also very effective in balancing out casual items like jeans. However, I believe the biggest reason NHUSW has gained so much support is the comfortable fit that makes you want to wear it again and again, and the wide range of sizes that makes it easy to incorporate into a variety of outfits."

The importance of choosing a size that suits your style, not just your body type.

NHUSW's collection offers a wide variety of styles, including short sleeves, three-quarter sleeves, and long sleeves, as well as different neckline shapes such as crew necks, V-necks, and boat necks. Their basic items, such as T-shirts and long-sleeved shirts, are meticulously crafted, from their unique fabric development to pattern making. While the designs are thoroughly streamlined, they boast a wide range of sizes, from 32 (XXS) to 44 (XXL), a total of seven sizes. However, this isn't intended to cover a broad range of body types, from petite and slender individuals to tall and well-built people.

"I recommend this to our customers, but even for myself, the '22RCH' five-quarter sleeve T-shirt I'm wearing today as an inner layer under my jacket is a size 38, while when I wear it on its own, I wear a size 40 or 42. So even with the same model, I change the size depending on the coordination and whether I'm tucking it in or not."


Owning the exact same T-shirt model in different sizes—this is the true essence of the NHUSW brand. They don't really focus on the outdated concept of "just the right size," instead asking customers what kind of shape and style they want to wear it in, and then suggesting the best model and size combination each time.

"For example, with this staff member wearing '16RCH,' I think the 'just right size' for him when he wants to look sharp with slim-fitting pants is size 36. But if he wants to create a sophisticated, relaxed look with slightly wider pants, then three sizes up, around size 42, would be just right. The impression changes completely depending on the size, and I also recommend changing sizes depending on the season. Even if you simply want a more relaxed silhouette and want to size up, I don't think there's any other brand that offers such a wide range of sizes, so I hope you enjoy choosing a size that suits your styling for the day and the balance that feels comfortable for you."


Furthermore, Kawasumi points out the sophisticated texture of NHUSW's items, which are unlike typical underwear.

"Both the '22RCH' and the '16RCH' use a rare and high-quality extra-long staple cotton called Suvin Gold for the body. Its luxurious, lustrous appearance is appealing, and it exudes an elegance that sets it apart from typical jersey underwear."

Furthermore, the fact that they also offer the same style in a smoother, more lustrous cotton and lyocell fabric (21RCH) adds a sense of "depth," which is another factor contributing to NHUSW's popularity. Indeed, with this, you can thoroughly explore your own preferred "basics" in terms of color, shape, fabric, and size, and perhaps even get a feeling of having something made to order.


"Moreover, if you take good care of it and continue to wear it, it won't lose its shape or the texture of the fabric will be damaged easily, so I think this excellent durability is also an important point."

What kind of state of mind did I reach with size "50"?

NHUSW's collection is already available in seven sizes, from 32 to 44. The new size 50 will be added to this lineup, featuring three popular styles reimagined in a larger size to better suit current styling trends. In today's world, where oversized silhouettes with a strong street vibe are prevalent, especially among high-end brands, this new size could be considered a "standard" in a sense, but it also seems to embody NHUSW's unique attention to detail.

"For NHUSW, whose concept is 'underwear that can be worn as the bare minimum outerwear,' it's very important to be able to get the 'best' and 'just right' piece at any time, regardless of the season. However, in a world where trends and styles are constantly changing, it's equally important to provide timely models, materials, and silhouettes."


NHUSW has consistently innovated by offering various new propositions on a sporadic basis, rather than resting on its laurels as a staple brand. These include wool versions of classic models and versions utilizing functional materials with UV protection and cooling effects. It seems almost inevitable that such a brand would develop a size 50, which offers an elegant oversized silhouette without being overly casual. It's surprising that they hadn't offered this size before, as the staff members wearing the "16RCH" in size 50 look natural and yet feel exquisitely fresh and distinctly NHUSW.


"We've seen an increase in customers who had never worn 'oversized' sizes before, but have started to embrace bold, oversized silhouettes. This led to a lot of demand for modern, oversized NHUSW clothing. What was needed for that wasn't a size 46 or 48, but a size 50."

While boasting a fashionable, street-style oversized fit, the fabric, made from Suvin Gold cotton, exudes a rich sheen, resulting in a beautifully flowing, oversized silhouette. Furthermore, in conjunction with the dramatic increase in size, the patterns and details have been meticulously reconsidered, creating a refined finish that could almost be described as a "redesign."

"A half-hearted size increase won't fit the intentions of customers who want to change their style or silhouette. Also, many people who usually only wear wide-legged pants or prefer a street style choose NHUSW because they want a T-shirt with a higher quality fabric than usual. We believe that NHUSW's signature oversized silhouette is a 'perfect fit' for the needs of such customers."


This exquisite size and silhouette makes it incredibly versatile; paired with wide-leg pants, it creates a relaxed yet elegant look. When paired with slim-fit pants, it results in a high-contrast, sharp, and edgy style.

NHUSW's collection is full of subtle details that are recognizable without being ostentatious, such as the brand label on the back of the collar and the center back seam. With its design, material, silhouette, and even a bold oversized feel, this size 50 item is sure to be a perfect piece that can be enjoyed in a variety of ways, as underwear, casual wear, or outerwear.
