Two simple steps

Stand straight by a wall, your shoulder blades touching the surface, but comfortably relaxed.

1. Underbust

Exhale and pull a measuring tape quite snug around your ribcage, just under your bust, where the breast tissue ends. This is your underbust measurement:

2. Overbust

Pull the tape around the fullest part of your breasts, making sure the tape is parallel to the ground. Breasts are a soft tissue, so this time do not pull the tape too snug. This is your overbust measurement:

Now, let’s pick a good starting point for your bra fitting at home:

Snug Fit

? Recommended starting point
for soft ribcage.

Comfy Fit

? Recommended starting point
for firm ribcage.

You might be surprised with the size above. No worries! This is just a starting point in the brafitting process. Once you get your new bra, we will help you find out how to proceed further.

If your breasts are full on the bottom, you’ll get different overbust readings with or without a bra, and that’s totally normal! For better accuracy in determining your starting size, you might take your overbust measurement while bending over 90 degrees, without a bra.

Treat this conversion chart as a starting point, not the ultimate size picking tool. Different lingerie manufacturers use different size standards, so a 32D with brand X is very often slightly different than a 32D with brand Y. That's why comparisons are just approximations.
