The Essential Trusst Bra Fitting Guide

 Editor’s note: Get ready for a good read. This blog post has everything you’ll need to help you find the right size, and style, that works for you.

Every woman is familiar with the struggle of searching for the perfect fitting bra. You head into dressing room after dressing room, trying on different styles in the hopes of finding “the one.” Push up, convertible, T-shirt, balconette, the ever-elusive try them all, yet you still find yourself walking away with bras that leave deep grooves in your shoulders or ride up when you lift your arms.

Like your favorite pair of jeans, the right bra can make or break the way you feel throughout the day. An ill-fitting bra can cause countless problems, from straps that constantly slip down your shoulders to underwire that digs into your ribcage – not to mention a band that won’t seem to stay put no matter how tightly you fasten it.

If you’re facing these issues, you are not alone: An estimated 80% of women are wearing the wrong bra size. Take it from Oprah, who, in 2005, pioneered a bra revolution in which she urged women across the United States to “rise up and get a proper bra fitting.” And with the average American bra size increasing thanks to a better understanding of correct sizing, it seems there’s no time like the present to heed Oprah’s advice and finally find your perfect fit.



A surefire way to tell if you’re wearing the correct band size is to conduct the band test: Stand in front of a mirror and look at how your bra band sits against your body. A well-fitting bra should have a band that fits snugly against the body and is level and parallel to the floor. And you should only be able to fit two fingers underneath the band – any more than that means your band size may be too large.

Secondly, look at your cups to see if your cup size is accurate. Your breasts should fill up your cups exactly. If your cups are gaping or puckering from being too large or, conversely, are causing a “quad-boob” effect (spillover from the top or sides of your bra) from being too small, then it’s time to reevaluate. 

If, after evaluating these two factors, you think you’re wearing the wrong-sized bra, it’s time to take new measurements!

At Trusst, we’ve put together this easy-to-follow bra fitting guide to help direct you towards your proper Trusst bra size. We believe that finding your size should be a cinch, and we’re committed to leading you towards your perfect fit so you can get the all-day comfort that you deserve.



You’ll need:

  • Your best-fitting bra (the bra should be non-padded and non-minimizing)
  • Measuring tape

Ensure that the tape is always parallel to the floor when taking measurements. Record all measurements to the nearest quarter inch. Handy tip: use a mirror to ensure the measuring tape is level with the ground and isn’t slipping in the back.

To measure your band:

  1. Stand up straight and relax. Don’t try to protrude or suck in your ribcage – breathe normally and comfortably.
  1. Wrap the tape around your ribcage; ensure it sits snugly beneath your breasts. You may need to lift your breasts in order to position the tape correctly. This measurement corresponds to your band size.

To measure your bust:

  1. Wrap the measuring tape around your back and measure at the fullest part of your bust (typically across the nipple). Write down this number.
  2. Head over to our bra fitting calculator, the Size Calculator, to find your size and measurements! (Note that the exact size you wear may vary from the current bra you are wearing.)



Once you’ve calculated your bra size, it’s time to find a style and shape that works for you!

Trusst bras are engineered to provide D+ women with maximum comfort, support, and style. Our bras are made with fuller-coverage, foam-lined cups to prevent show-through and wide, buttery-soft straps that reduce shoulder strain. Additionally, all of our bras are specially fabricated using our patented support system. It lifts over 80% over your breast weight and redistributes this weight evenly across your core, and replaces underwires so you’ll never have to deal with poking wires again! Lastly, Trusst bras are all crafted from our signature moisture-wicking, antimicrobial jersey lining, designed to keep you cool and boob-sweat-free.

Far from your standard everyday T-shirt bra, the Marjory is crafted to be ultra-comfortable and ultra-versatile. Currently offered in a cream shade, this bra promises to keep you supported no matter the occasion.
