Meet the Updated Seashell Balconette One-Piece
Our Seashell Balconette One-Piece swimsuit is known for its structured, feminine design and supportive fit. The balconette shape is specially created to offer lift, contour, and a flattering silhouette—making it one of our most loved styles.
Now, this signature piece is even better.
We’ve introduced new cup sizes designed to provide:
- improved bust support
- better coverage
- a more precise and comfortable fit
If you’re unsure what cup size works best for you, we recommend reading our guide:“Are you wearing the right swimwear cup size?” — a simple step-by-step article that helps you measure correctly and understand your ideal fit.
The extended cup size range is currently available in four of our most popular shades:
By launching these updates in our core colors, we’re able to focus on perfecting the fit and ensuring consistency across all sizes—while maintaining the same premium look and feel you expect.
Introducing Size XL
Alongside the new cup sizes, we’ve also added a new overall size: XL.
This addition is part of our commitment to more inclusive swimwear sizing, allowing more women to find a piece that fits comfortably without compromising on support or design.
We understand that every body is different, and having more size options means:
- better comfort
- improved support
- a more flattering fit
Why the Right Swimsuit Fit Matters
Choosing the right swimsuit size and cup isn’t just about measurements—it directly impacts how you feel.
A well-fitted, supportive swimsuit can:
- enhance your natural shape
- provide proper bust support
- eliminate discomfort and constant adjustments
- boost your confidence
That’s why expanding our size range was such an important step for us.
Designed for Fit, Not Just Size
At Noire, extending sizes doesn’t simply mean scaling up or down. Each new size is carefully developed to maintain:
- the same level of support
- the same design proportions
- the same premium quality
Because a great swimsuit should feel just as good as it looks—no matter the size.

This extended size range is only the first step. We’re continuously working on expanding cup sizes and swimwear sizing across more styles and colors, guided by your feedback.
Our goal is simple: to help every woman find a swimsuit that fits beautifully, supports naturally, and feels effortless to wear.
