Bra Fit

You have probably all heard the statement that 80 percent of women are wearing the wrong size bra. It is probably true, since instructions for measuring the fit found on the web vary considerably. Many stores that sell bras don’t know how to properly fit them either, so it is important to know for yourself what your best size is and how to tell if a bra fits correctly. Different manufacturers have different sizing systems, so it is essential to try on any bra before buying- don’t just go by the size on the tag.

Here are some of the better resources I have found for finding a properly fitting bra:

  1. Hello,

    The bra size converter at 85B is wrong. They list UK sizes using a US scheme. The UK doesn’t include I and it uses double letters after D, while the 85B calculator includes I and does not use double letters.

    I didn’t see a way to contact the site itself, unfortunately. Their feedback link is broken.

  2. Thanks for pointing that out, Adventures. I have changed the link to a conversion chart from that appears better. Please let me know if you see any other problems.
