Designed for everyday wear, not just occasional use. This brace gently supports your shoulders and upper back, making it easier to stay aware of your posture while you work, move, or unwind at home. Lightweight enough to forget you're wearing it. Supportive enough to actually make a difference.
STEP 1: Slip On
Place the straps over your shoulders just like wearing a backpack.
STEP 2: Adjust Waist
Secure the primary abdominal band firmly but comfortably around your ribs.
STEP 3: Tension Shoulders
Pull the secondary shoulder straps forward to reach your desired alignment.
STEP 4: Final Check
Ensure the brace feels snug yet allows for full, deep breathing.
The adjustable straps let you personalize the fit around your shoulders, upper back, and under-bust area. It should feel gently supportive, never tight or uncomfortable.
Use your under-bust measurement and height together to find your best size. When in between sizes, go with the larger one for a more comfortable fit.

I've tried three different posture correctors before this one. One was too stiff, one dug into my armpits and the other looked so bulky under clothes that I stopped wearing it. This one just feels better made to me. The fabric, the straps, even the way it sits across the back feels more thought out. I still adjust it depending on what I'm wearing, but this is the first one I've actually kept using instead of throwing in a drawer.

I'm 64 and I've become much more aware of my shoulders rounding forward these last few years. What surprised me with this one is the area under the arms. That's usually where these things start bothering me. So far this has been much easier for me to wear.

Love this. The pink is even prettier in person and it fits really well. I'm going to try the beige one next just to see how I like it under lighter clothes, and honestly I'll probably get another pink too.

By about 2 or 3 in the afternoon I'm usually hunched over my computer without even realizing it. This gives me that little reminder to straighten up. It doesn't feel like something is forcing my shoulders back, which is what I was worried about.

I honestly thought this was going to show through everything I own. It doesn't. With a normal loose top I barely notice it, and neither does anyone else. That was a big deal for me.

I picked the wrong size on my first order. Totally my mistake. I emailed customer service and they gave me 100% store credit so I could get the size I actually needed. The new one fits much better. I wasn't expecting the whole thing to be handled that easily, so I wanted to mention it here.

Hand wash gently in cold water and let it air dry. Avoid bleach, tumble drying, or high heat to help protect the fabric and shape.
It should feel secure and gently supportive, not tight, painful, or restrictive. You should be able to breathe, move, and sit comfortably.
