Nstyle, the 'Non-Flattening' Bust-Flattening Innerwear, Celebrates 5th Anniversary: Five Years of Supporting Individuality

Nstyle (Enu Style), a bust-flattening innerwear brand operated by Ellerose Co., Ltd. (Headquarters: Fukui City, Fukui Prefecture), will mark its 5th anniversary since brand launch on Sunday, June 28, 2026.

To express gratitude for the support received over the past five years since its 2021 launch, a limited-time campaign will be held. We also reflect on our journey so far.

Five Years Rooted in the Idea of 'Not Flattening'

Nstyle was born to support those who, for various reasons, wish to make their bust appear more compact and smaller—a completely new category of 'bust-flattening innerwear' unlike anything before. While the belief that 'breasts should be large, beautiful, and well-shaped' remains deeply rooted, many people feel discomfort or struggle with this norm.

Through its approach of 'supporting without flattening,' Nstyle has offered a new choice in underwear, enabling people to be their most comfortable selves.

Our Journey Alongside Customers

- Expansion of Product Lineup

Starting with the original half-tops and tank tops, we have expanded our offerings based on customer feedback, adding color variations, open-neck half-tops, sports tops, V-neck styles, and more.

- Product Development Driven by Customer Voices

We actively listen to real customer feedback through focus groups, surveys, and social media, using these insights to improve existing products and develop new ones. By prioritizing the user’s perspective, we continue to evolve the brand.

- Creating Real-Life Experience Opportunities

While primarily online, we have hosted pop-up events to provide opportunities for customers to try on products in person. These events go beyond simple fitting—they’ve become spaces where people can share concerns about their busts or fashion insecurities, helping customers reflect on their feelings and move forward positively, earning high praise.

- Multiple Awards Received

Nstyle has been recognized not only for its functionality and comfort but also for its social significance in supporting diverse values, earning numerous awards:

・Good Design Award 2023 (2023)

・IAUD International Design Award 2023, Silver Prize in Fashion Design (2023)

・Social Products Award 2024, Social Products Prize (2024)

・JAPAN DIRECT AWARD, Social Category Prize (2026)

- Patented Original Structure

Nstyle holds a patent (No. 7780819) for its unique bust holder panel structure, which supports and naturally shapes the bust without flattening. This official recognition validates Nstyle’s proprietary technology that balances comfort with a flat silhouette, assuring customers of a trustworthy product.

Customer Voices Reflecting Impact

Among the many customer testimonials received:

- 'My clothing choices have expanded'

- 'I can now live without worrying about my chest'

About Nstyle

'Nstyle' is a bust-flattening innerwear brand created to support those who wish to make their bust appear more compact and smaller for various reasons. Developed by Ellerose, a company with extensive experience in beautifully enhancing busts through shapewear, Nstyle features two carefully designed bust holder panels. It firmly supports the bust from below while distributing volume upward, achieving a healthy, flat bust silhouette with comfortable wear.

Today, while understanding of fashion and gender identity diversity is growing, the belief that 'breasts must be large, beautiful, and well-shaped' still persists. In a society that unconditionally demands so-called 'femininity,' Nstyle offers a new choice—underwear that helps people be their most comfortable selves.
