Finding Your Size

Because the purpose of a NABAY chest binder relies solely in the sizing and fit according to your body type, we recommend taking extreme care when measuring yourself, rather than relying on past measurements or guesses.

Therefore, we've included this step-by-step guide on how to measure your bust, which can then be cross referenced with our Sizing Chart.

† We adhere to the new European standard of sizing (EN 13402), so all sizes are in centimeters.
‡ Japanese sizes often run small, so a Small in American or European sizes might be Medium in Japanese.

How to measure for a NABESHIRT

  1. Measure around your chest just below the swell of your breast. Make certain the measuring tape is snug, but not constricting.
    This measurement is your underbust, as shown by the red line in the diagram.

  2. Now measure around the fullest part of your breast. The tape should be loose-fitting, as when measuring for a bra.
    This number is your topbust.

  3. Subtract your underbust size from your topbust size. This number will give you your cupsize, according to the chart below.

These measurements are approximate. Just find the number closest to the difference between your topbust and underbust.

Now that you have your cupsize and underbust size, you need to consider a few more factors for choosing your correct NABAY size.

  • What is your overall body type?
  • Have you, or do you plan to, lose or gain weight?
  • Have you ever had chest related illness, such as asthma, or chest surgery, or difficulty breathing?
  • Do you, or do you plan to, begin a regimen of hormone treatments?
  • What kind of support are you looking for? Fully restrictive support, for occasional use? Or an everyday garment with a more natural, looser feeling?

Once you have answered these questions, you should continue on to the Sizing Chart.
