Our Story

Our love story began in the rich seas of Northeastern Japan, where the three waters of the world embrace, and nature in all her beauty and diversity flourishes. Here in the majestic fields of green, swaying Wakame seaweed, nature has seen fit to gift us one of her great, nutrient-rich treasures. A small, miraculous ocean botanical known as Mekabu. Harvested for centuries by Japanese farmers for its health-giving properties, this marine miracle inspired MASAMI. For the ultimate in botanically hydrated hair.

MASAMI: “Truly Beautiful”. Hydration Is Life.

Love, MASAMI

Size Guide

In between sizes? Keep in mind that swim fabric expands! If you're in the water A LOT, select the smaller size for a supported, secure fit. If you're more likely to dive into a great book than a pool, choose the larger size for maximum comfort in the sun.

TORSO SIZING

Using a soft measuring tape, measure the length of your torso from your shoulder (where a bra strap typically lands) to between your legs (where the inseam of your pant legs meet). If you are over 30," you might prefer Andie long torso fit.

Some women know they have a long torso because one piece swimsuits tend to ride up or dig into the shoulders, or even feel too deeply scooped in the bust...If you are often adjusting the length of the suit (tugging and shifting) you may be a long torso fit!


Flat

Flat

Compressive lining
Four-way stretch expands to fit your curves comfortably and hug your smallest measurements
Supportive all around, for a secure fit feeling
Expands slightly in water -- great fabric for wearing in and out of water

Ribbed

Ribbed

Compressive lining with self rib that is more expandable
Four way stretch expands to fit your curves comfortably and hug your smallest measurements
Super flattering with texture stripe elongating and lengthening

Eco

Eco

Eco fabric is a blend of 87% Recycled Polyester (made from recycled post-consumer plastic) and 13% Spandex to mimic our Flat fabric's compression, stretch, and handfeel.

Bloom

Bloom

Bloom is a knit jacquard fabric made of 33% Nylon, 57% Polyester, and 10% Spandex, making it more delicate than our Flat and Ribbed fabrications. Bloom fabric will darken when wet, but return to original color after drying. This fabric runs true-to-size, but if you're not sure - stick with a size up.

Terra

Terra

Terra has an abstract, stone-like texture with the comfort and stretch of our classic Flat and Ribbed fabrications. This 97% Polyester, 3% Spandex fabric is double-lined, giving you flattering compression and control.
