What should I expect after wearing it on the first day?Updated 4 hours ago

Don't be surprised if you barely notice it at first. When you first 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, you may notice your upper back feels 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, exactly like a light workout you didn't have to think about.
