Find your new feel-good bra with the BFF (Best Fit Finder): our Aerie-exclusive way to measure your bra size. Watch Iskra show you how to use it, or follow the steps below. All that matters? Finding the bra that feels best!

Before you start, make sure you’re in a lightly lined bra and a tight top, bodysuit or no top. No push up bras or bulky sweaters for this!

Step 1: Find your band size.

Use “This side first!” on the BFF.  Wrap it around just under your bust, making sure the top of the tape is aligned with the bottom of your bra band.

Step 2: Find your cup size.

Use “This side second!” on the BFF. Wrap this side around the fullest part of your bust, and line up the bottom of the tape with the top of your bra band. In the column where the edge of the tape lands, look for the band size you measured in Step 1. The letter next to it is your cup size, and that’s it! You have your Aerie bra size.

Step 3: Find your sister size.

The BFF also gives you your sister size, aka another size you can try to see if it feels good. To find your sister size, check out the color-coded diagonal boxes extending off of the original size you measured. You can try these sizes for a similar fit to the one that you measured.

Get your BFF here. Need a little extra help? Visit us in stores for a custom, free fitting any time.
