Our Approach

Built around the fit.

Beautiful swimwear begins with thoughtful engineering.

Every Mosona design is created with the needs of fuller busts in mind because true support isn’t an afterthought—it’s the foundation.

Our goal is simple: create swimwear that feels as good as it looks, so you can think less about adjusting your swimsuit and more about enjoying where you’re wearing it.

Not sure of your size?

Start with the calculator: two tape measurements — snug under the bust, then level around the fullest part — and about 2 minutes. It applies the same method Linette uses in real fittings, tells you a starting size, and flags whether that result sits inside the launch range — bands 30–40, cups DD–H.

Not sure of your size? Two measurements settle it.

A tape, a mirror, and about 2 minutes — the calculator turns your underbust and bust measurements into a starting bra size, and tells you if it’s in our launch range.
