Shopping for bras internationally, especially from Japanese brands, can be a delightful experience but also a bit confusing due to differences in sizing systems. Japanese lingerie brands are renowned for their high-quality designs, luxurious fabrics, and attention to detail, making them a favorite for women worldwide. However, understanding Japanese bra sizes is crucial to ensure a perfect fit. This guide will help you convert your bra size to the Japanese sizing system effortlessly.
Understanding Japanese Bra Sizes
Japanese bra sizes follow a slightly different format compared to Western systems, such as those used in the US, UK, or Europe. Here are the main components of a Japanese bra size:
- Band Size: Measured in centimeters and typically ranges from 65 to 100.
- Cup Size: Denoted by letters such as A, B, C, etc., but the actual measurements may differ from Western cup sizes.
Key Differences Between Japanese and Western Bra Sizes
- Band Size: Japanese band sizes are calculated using the underbust measurement in centimeters. This differs from the US/UK systems, which use inches and may include vanity sizing.
- Cup Size: The cup size in Japan is determined by the difference between your underbust and bust measurements in centimeters. Each letter typically corresponds to a 2.5 cm difference.
For instance:
- An underbust of 70 cm and a bust of 82 cm results in a 12 cm difference, equating to a Japanese B cup.
How to Measure Yourself for Japanese Bra Sizes
Step 1: Measure Your Underbust
Use a soft measuring tape and wrap it snugly around your ribcage, just beneath your bust. Write down the measurement in centimeters.
Step 2: Measure Your Bust
Place the measuring tape around the fullest part of your bust. Ensure the tape is level and not too tight. Record this measurement in centimeters as well.
Step 3: Calculate the Difference
Subtract the underbust measurement from the bust measurement to determine your cup size.
