Bra size labeling differs between the U.S. and Japan. At a glance, the numbers and letters appear reversed!
Labeling in Japan uses cup size (B) followed by underbust size (65 cm).

It's easy to measure your size under Japanese labeling! So, Let's try!

In order to properly measure your size, wear one of your usual bras and then, with a measuring tape, measure the circumference of your chest at the fullest point and directly under your bust. Use the measures you obtained to look up your size in the chart.

1:Measure your bust horizontally.
2:Measure your underbust horizontally.

Now you see why the U.S. band size to Japanese band size isn’t going to be a simple conversion of inches to cm? Because American band size is measured in this way, it will most likely be a greater number than your Japanese band size.

① Measure your bust horizontally.

While looking in the mirror, straighten the measuring tape so that it is level with the floor, bend slightly forward, and measure at the highest point of your bust.

Once you are bent over and the measuring tape is aligned with the highest point of the bust, raise your body and check again that the tape is level and straight, and take your measurement!

② Measure your underbust horizontally.

*underbust = the circumference of the bust just below the bust point

While looking in a mirror, straighten your back and make sure that "the measuring tape is level with the floor", and place it right along the bottom of the bust point. Check both sides!

Tighten the measuring tape just enough so that it feels a little tight and measure precisely. Don't forget to check in front and behind to make sure the tape is aligned properly.
