To keep your posture bra in great shape and lasting as long as possible, wash it in cold water and tumble dry on low. Better yet, hang dry it. That keeps the fabric at its best and uses less energy, which is a little kinder to the planet too.

Measuring yourself takes just a minute and gives you the most accurate fit. Grab a soft measuring tape and follow these three steps.

Step 1 -- Your band (ribcage). Wrap the tape around your ribcage, just under your armpits where a band sits. Keep it level, breathe out, and take the smallest number. That's your band.

Step 2 -- Your bust. Wrap the tape around the fullest part of your bust, keeping it level to the floor, and note that number.

Step 3 -- Your cup. Subtract your band from your bust. The difference is your cup size (1" = A, 2" = B, 3" = C, and so on).

Put them together, band plus cup, and that's your bra size. Then check it against our size guide to find your recommended size. One thing to note: Etalon measures the ribcage just under your armpits, which is a little different from how most bras are sized. That placement is intentional, since it's what lets the bra deliver real, supportive posture feedback from the back. If you're ever unsure, email us at hello@etalonposture.com and we'll happily help.

Getting the right size really is key to great results, so this is a good question to ask. If your measurements land between two sizes, we recommend sizing down. Etalon is designed to work through a gently compressive, supportive fit, and the smaller size gives your postural muscles the right amount of engagement to do their work.

When in doubt, don't guess on your own. Send us your measurements at hello@etalonposture.com and we'll help you find your best fit.

We completely understand the confusion - it's not the usual spot! Most bras are measured under the bust, so our method can feel a little unexpected.

Etalon uses an upper rib cage measurement because our posture support system works through the upper back and shoulders. Measuring higher on the rib cage helps ensure the bra provides the right level of support where it's needed most. 

Beyond the obvious causes like a few extra pounds or accidental shrinkage from a hot wash, your body naturally fluctuates in ways that can affect the fit. Here are the most common reasons:

Your cycle. In the days around your period, your body retains more fluid and your breasts can swell, which may make the bra feel snug. If it gets uncomfortable, simply take a break from wearing it until your period passes.

Hormonal changes during perimenopause. As estrogen and progesterone shift during perimenopause, your body composition and water retention can change, and your ribcage and bust size may change along with them. If this is you, your original band size may genuinely feel too tight, and it might be time to re-measure.

After a COVID vaccine or booster. A vaccine can temporarily cause the lymph nodes under your arms to swell, which can make wearing a posture bra uncomfortable. This happened to our founder! Just pause your wear until things settle back to normal.

The good news is that in most of these cases the tightness eases on its own. If it doesn't, re-measure using our size guide or reach out and we'll help you with a new size.

When you first put on your Etalon bra, you should feel gentle support rather than a strong pull, almost like a soft, steady hug around your shoulder blades. That subtle sensation is the bra doing its job. Instead of yanking your shoulders back, its patented scapular guidance gently stabilizes and guides your shoulder blades toward their natural position, while your own upper-back muscles do the real work of holding you upright.

Don't be surprised if you barely notice it at first. When you put it on, you're naturally paying attention to your posture, so the cue feels quiet. As your day goes on and that awareness fades, Etalon gently encourages your postural muscles to re-engage in the background. By the end of the day, your upper back may feel more awake, or even a little tired. That's a good sign. It means your muscles are doing the work they're meant to do.

Think of it as a posture trainer, not a corrector. The goal is light engagement and awareness that builds real strength over time, never forced correction.

It's built for cup sizes E - H (as well as pregnant and nursing mothers navigating size changes) and features wide straps that distribute your bust's weight evenly across your shoulders - no painful indentations.

The Etalon posture bra doesn't include padding -- and that's intentional! When developing the bra, we spoke with many women and found that preferences vary quite a bit. Some love the added shape and support that padding provides, while others prefer a more natural feel without it. Rather than making that choice for you, we designed the bra with built-in pockets so you can customize it to suit your own body and comfort.

We don't sell padding separately, but you can use any bra insert you already own or pick one up from most lingerie or department stores.

For your first week or two, wear your Etalon bra on the loosest back strap setting for two to three hours at a time, ideally in one continuous stretch. This lets your body ease in gently while your postural muscles start to wake up.

You're looking for a soft pull, not a strong tug. If the support feels too subtle, tighten the back straps one setting at a time until you notice that gentle pull at your shoulder blades. That's your starting point, and it's exactly where the training begins.

A few things that help early on: try to wear it consistently rather than sporadically, since regular wear is what builds the habit. Pair it with movement like yoga or Pilates for even better results. And remember, Etalon is designed to train your muscles, not force your posture, so gentle and steady always wins.

Here's a quick guide to getting the most out of your bra:

•  Put it on like a regular bra with the straps at the factory adjustment. The shoulder seams should sit at your collarbones.

•  Draw your shoulders back gently until you feel a soft pull -- that's your starting point. You may barely notice it at first, and that's normal. As your day goes on, Etalon quietly encourages your postural muscles to re-engage. By the end of the day, your upper back may feel more awake or even a little tired.

•  Wear it a few hours a day to start -- ideally in one continuous stretch -- for the first few weeks.

•  As it starts to feel easy, tighten the straps one level to deepen the work.

•  Wearing it a full day (6+ hours)? Take the next day off. Muscles strengthen on the recovery, too.

Go by your measurements. Etalon measures the rib cage just under your armpits (above the bust), which is a little different from how most bras are sized. This placement is intentional -- it's what allows the bra to deliver functional, supportive posture feedback from the back.

Grab a soft tape, measure your rib cage on the exhale (take the lowest number), then measure the fullest part of your bust. Subtract the band from the bust for your cup size (1" = A, 2" = B, 3" = C, and so on), and match your numbers to our size guide. If you're ever unsure, email us at hello@etalonposture.com.

The Etalon bra is designed for a gently compressive, supportive fit, so it may feel a touch snugger than a regular bra. That's intentional, and it's part of how the bra supports your alignment and gives your postural muscles something to work with. Because of that, we always recommend measuring rather than going by your usual size, so you land on the fit that works best for you.

You don't need another bra -- Etalon is designed to be worn on its own. Its supportive, compressive fit is comfortable for everyday wear, and the built-in pockets let you add optional inserts anytime you'd like more shape or coverage.

That said, it's really an either/or. Layering it over a regular bra isn't ideal since the regular bra's straps would show underneath Etalon's back straps.

Everyone's skin is different, so we'd suggest wearing it for just a couple of hours on your first day to see how your skin responds before committing to longer wear. Our fabric, straps, and hooks are all PFAS-free and fluorine-free, the material composition is latex-free, and the bra is FDA registered. If you notice any irritation, please stop wearing it and let us know so we can help you.
