Everyday comfort for women, simply made

Smart River Shore is a small Tokyo studio making soft, plain everyday basics for women: bras, briefs and simple sets in cotton and modal.

Advantages

We choose soft cotton and modal fabrics and keep the seams flat, so each piece stays comfortable through a long day.

Thoughtful Fabrics

Soft materials that breathe, kept plain and easy to wear.

Simple Fits

Our everyday bras skip heavy wires and tight bands and aim for a smooth, relaxed shape.

Calm Design

No loud logos and no complicated fastenings. These pieces are made to be worn and forgotten.

What We Do

Smart River Shore is a small studio in Tokyo making plain underwear for women: everyday bras, briefs and simple matching sets. We keep the designs quiet, with soft fabric, flat seams and no logos on show.

The range is small, so each piece can be described properly. If you want to know more about a piece, its fabric or its size, write to us at the address below.

How We Work

We describe each piece in plain words and show our prices and contact details openly. We would rather give you a short, honest description than long sales copy, so you will not find rankings, awards or big promises on this site.

Questions about a piece, a size or an order can go to the email address or phone number at the bottom of the page.
