EF Cup Bra Collection
Japanese Lingerie — EF Cup Guide
About EF Cup Bras
EF cup bras are designed for women with a fuller bust — typically a difference of 18 to 25 cm between the underbust and bust measurements. Finding well-fitting, elegant lingerie in EF cup sizes can be a challenge, particularly outside Japan. Our EF cup collection addresses this directly, offering beautifully crafted sets that combine proper support with refined feminine styling.
At Body Secret Garden, our EF cup collection is conceived and developed by Japanese designers, planned in full accordance with Japanese quality and safety standards. Each piece features reinforced underwire construction, wider side panels for stability, and adjustable straps — all designed to provide all-day support without sacrificing elegance. The delicate lace and embroidery detailing reflect the Japanese tradition of making even functional garments beautiful.
Our EF cup range includes a variety of styles — from classic ivory and navy lace sets to bold embroidered designs — so that women with fuller figures can enjoy the same quality and variety as any other size.

Frequently Asked Questions
What is an EF cup bra?
An EF cup bra refers to bras fitting Japanese E and F cup sizes. These are fuller-bust sizes with a bust-to-underbust difference of approximately 18–23 cm. In UK and US sizing, Japanese E cup corresponds to DD, and Japanese F cup corresponds to E cup.
Is Japanese EF cup the same as international sizing?
Not exactly. Japanese cup letters are one step behind UK/US labelling. Japanese E = UK/US DD, and Japanese F = UK/US E. Band sizes are also measured in centimetres in Japan rather than inches. Our Size Guide provides a complete conversion table to help you find the right fit.
Are EF cup bras hard to find in elegant styles?
In many markets, yes. Fuller-bust bras are often designed purely for function, with limited styling options. Japanese lingerie brands have long recognised this gap, producing EF cup styles with the same delicate lace, embroidery, and feminine detailing as smaller sizes. Our collection reflects this philosophy.
Do you ship EF cup bras internationally?
Yes. We ship worldwide from Japan. All orders are carefully packed and dispatched within 2–3 business days. Shipping costs and estimated delivery times are calculated at checkout based on your destination.
