BCD Cup Bra Collection
Japanese Lingerie — BCD Cup Guide
About BCD Cup Bras
BCD cup bras are designed for women whose bust measurement falls within the small-to-medium range — typically a difference of 10 to 20 cm between the underbust and bust measurements. This range covers Japanese cup sizes B, C, and D, which correspond closely to international B, C, and D sizing used in the UK, US, Australia, and most of Europe.
At Body Secret Garden, our BCD cup collection is conceived and developed by Japanese designers, planned in full accordance with Japanese quality and safety standards. Each set pairs a structured bra with a matching panty, offering both everyday elegance and all-day comfort. Our underwire designs provide gentle lift and shape, while the lace detailing adds a refined feminine touch that is distinctly Japanese in character.
Whether you are looking for a classic floral lace set, a romantic embroidered style, or a bold black-and-white design, our BCD cup range offers a variety of colours and patterns — all made to the exacting quality standards Japanese lingerie is known for worldwide.

Frequently Asked Questions
What is a BCD cup bra?
A BCD cup bra refers to bras designed to fit B, C, and D cup sizes. In Japanese lingerie sizing, these cups are measured by the difference between your bust and underbust circumference. BCD cup bras are the most common size range and suit a wide variety of body shapes.
Do Japanese bra sizes match international sizes?
Japanese cup letters (B, C, D) correspond directly to UK, US, and Australian cup letters. However, Japanese band sizes are measured in centimetres rather than inches — for example, a Japanese 75B is equivalent to a UK 34B. Our Size Guide includes a full conversion chart to help you find your perfect fit.
Do you ship BCD 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.
What makes Japanese lingerie different?
Japanese lingerie is known for its exceptional attention to detail — precise stitching, premium lace fabrics, and designs that balance femininity with everyday comfort. Body Secret Garden sources pieces that reflect this tradition, offering quality that is difficult to find outside Japan.
