What’s different about Trusst bras?

Trusst bras are anchored in science. They contain a revolutionary technology that is engineered to support over 80% of breast weight from underneath your breasts. This technology reduces pain points caused by traditional underwire bras such as poking wires, shoulder dents, or back and neck pain. In addition, each bra is lined with an anti-microbial and wicking fabric, cutting down on boob sweat to keep you fresh and dry all day.

Do your bras have padding?

Our bras contain a light layer of padding over the 3D support structure that is sewn into the cup. If you are feeling discomfort from the structure, this may mean that the band is too tight. Our Bra Experts are available to help with sizing issues and more information on how to exchange - please email us at


Does your bra have underwire?

Our bras do not contain traditional metal underwire. Instead we use a plastic, patented 3D technology that is molded into the cup. This structure lifts up to 80% of breast weight from underneath your breasts by using the core of your body. Our technology helps to reduce typical discomforts caused by underwire (or wire-free!) bras, like back and shoulder discomfort.  


Can you feel the support structure?

You can tell that there is a structure in there by the way it is lifting and supporting your breast weight. If the fit is accurate you should not feel discomfort. If you feel discomfort from the structure or feel that it is noticeable when wearing the bra for a period of time, the fit may be off. We can help you find the right fit - please email and someone on our team will help you with sizing.


Do Trusst bras fit true to size?

Trusst bras fit differently than other brands due to the structure that is molded into the cup. The technology in our bras creates a more shallow cup. We have determined that our cup sizes tend to run a bit small, you can see your Trusst size and "other" size in the chart below. We always encourage you to reach out to our Bra Experts, who are happy to assist in any fit related questions you may have.

I tried your fit calculator, and I got a size that is totally different than what I currently wear. What should I do?

If you find that your suggested Trusst size is different than the size you normally wear, please email us at with your current size, brand of bra you are wearing, and your band and bust measurements and someone on our team will get back to you as soon as we can. We want to make sure you find the right fit, and we’re here to help!


I think I’m in-between sizes. What should I order?

If you think you are in-between sizes, we recommend that you purchase both so that you can compare the fit for each. We offer free returns and exchanges, so you’ll be able to return the size that doesn’t fit at no extra cost. Since our bra technology fits differently than an underwire bra, we encourage you to test out our bras as much as you can - we even want you to wear your new bra around for a few hours, or days, to really feel the difference our support makes before you decide if you want to keep your bra. If you have any questions once you have received your order, our Bra Experts will be happy to chat with you. Please email us at with any and all questions!


You don’t make my size. Will you ever expand sizing?

We are an emerging brand, so while we don't carry your size right now, we may expand our sizing in the future. We share all sizing requests with our design team and we take our customer feedback very seriously.


Do the straps stay in place?

Yes, our straps are designed to stay in place by the way the bra fits. They also have a lot of adjustment - the Naomi has 4 points (2 on each strap) for extra versatility and the Marjory has 2 points (1 on each strap). Our straps are made out of a soft elastic that feels comfortable against the skin. Most of the lifting is being done by the 3D support structure that is molded into the cups.


How do these bras do with boob sweat?

Our bras are lined with fabric that has antimicrobial and wicking properties to keep you feeling fresh and dry as the day goes on.
