How To Find Your Perfect Bra Size

VIDEO TRANSCRIPT: "How to find your perfect bra size" Length: 2:32

You try on a new bra, and the fit’s not perfect. So, what do you start changing? Your band size? Your cup size? Both? Here’s the answer.

The first thing you should always do with a new bra is make sure you’ve put it on correctly.

Lean forward, make sure your breast tissue is up and in the cups, and that the tips of your breasts are in the apex of the cups.

Then stand up.

The #1 bra fitting mistake women make is being in a cup size that’s too small.

So, assess your cup size first. Here’s why.

Changing your cup size is a small change — only 1” difference in your total body circumference.

So, while keeping the same band size, go up or down one cup size at a time to see if your fit is improving.

And, if you’re going up in cup sizes, I always recommend going up until you find a cup that’s too big.

Here’s an example.

Our model is in a size 34D bra. Many may think her bra fits just fine. It doesn’t.

Underwires are on top of her breast tissue instead of in her breast crease.

This is a full coverage bra, but on our model, it looks like a demi bra.

Her cups are too small.

So, let’s increase her cup size while keeping a 34 band:

34(D2), 34(D3), 34(D4),

and maybe 34(D5),

and maybe 34(D4).

This cup fits.

So, now we have her cup size — D3 on a 34 band.

So, now we have her cup size — D4 on a 34 band.

So, now we have her cup size — D5 on a 34 band.

But the back shows her band is way too large.

The #2 bra fitting mistake is being in a band size too big which can also cause your straps to fall off your shoulders.

A band size change is a 2” adjustment, and also changes the placement of your bra straps on your shoulders.

So, going up a band size also moves your bra straps closer to your shoulders.

Now, when you change your band size, you need to understand sister sizing — and this is where many women get confused.

Changing a band size means you must also adjust your cup size to keep the same cup volume.

This sister sizing chart explains what I mean.

Back to our model.

We left her wearing a 34 band and a D3 cup size.

We left her wearing a 34 band and a D4 cup size.

We left her wearing a 34 band and a D5 cup size — right cup size but her band is big.

So, we need to move up a cup size when moving down a band size to keep her cup volume the same.

To keep her cup volume the same and reduce her band size, we move from a 34(D4) to a 32(D5).

...we move from a 34(D5) to a 32(D6).

...we move from a 34(D3) to a 32(D4).

Cups fit, but the band is still a little too big.

Move to a 30(D6).

Move to a 30(D5).

Her cups fit, and the band is properly tight.

What a difference from her starting point.

Our model looks terrific in her perfect bra size, has much better support with a lifted and shapely bustline.

You too can find your perfect bra size.

Just remember to first find your cup size. Then, follow the sister sizing rules to find your band size.

How to Find Your Perfect Bra Size

Do you ever wonder if you’re in the right bra size, or if you could get a better fit from even your favorite bras if you made a few little changes? Oftentimes, women think they’re wearing the right size bra, when in fact, they are not.

In cases like these, all it usually takes to achieve a better fit is a little adjustment to the band size, cup size, and the way you put on and adjust your bra.
