You're trying to do everything and get on with your day, but all you can feel is your bra digging into your back, tight and uncomfortable. No matter how often you adjust the straps and pull at your underwire, you only want to get home and rip it off.

How To Measure Bra Size?

Fit First

Poorly fitted or wrong-size bras are the worst. And if you've got big boobs, it's the pits. Breast and back pain is real, so investing in a quality, well-fitting bra in cut and size is a game-changer. From brand to brand, bra size is as changeable as the weather; a B-cup here is a C-cup there. Bear in mind – bras can also change in size after a wash or even after you've worn them for a full day. The good news is that DeBra's has fitted bras for over 22 years and has the best tips for measuring your bra size. DeBra's founder will talk you through a few suggestions.

Be Your Breast Advocate

For the best fit and maximum support – know your bra size. These numbers are hard to remember, so it's best to keep a record of them on your phone. That way, your size is at your fingertips when you're buying online. Remember, the letters relate to cup size, and the numbers are your bra's band size. The band size should be the same or one size smaller than your regular clothes size.

What Does What?

Odds are, you're wearing the wrong size bra. Sorry – annoying but true – roughly 80% of women are wearing the wrong size. Like most clothing items, bra sizing is a guide only, and different brands can fit differently. Your best bet is to go by feel. 80-90% of your bra's support comes from the band around your ribcage. It must be firm but not tight in an 'I can't breathe' way. Most of us think the shoulder straps are the star of the support operation – not so. They help keep the breasts in place but don't carry the weight. If you cast the straps in the lead role, your bra will be uncomfortable and ultimately damaging in the long term. The same goes for the underwire; it's there to shape and keep your boobs separated, not to act as suspension or support.

Debra's Fit Tips

Bend forward while you hook up your bra. Doing this will guarantee your boobs are in the cups correctly and the wire isn't sitting on your breast tissue. When you adjust the band, your bra should be at the same level front and back – no riding up your body. Next, an easy test for a loosey-goosey bra: you should be able to slide only one finger under the band. If you can fit two, tighten. If your straps start slipping down your shoulders, tighten the band first before shortening the straps. If your bra is relatively new, tighten only the bra straps. As a rule, the straps need tightening almost weekly; they tend to wriggle down over time.

When you've had your way with all the hardware, it's time to look in the mirror. With a well-fitted t-shirt over your bra, you can see if the cups crumple or if there's bulging out the front. If so, your bra is the wrong size. Now turn sideways: your boobs should sit halfway between your shoulders and elbows. If they're too high or too low – that's a no-go. These red fit flags mean your bra isn't a good fit.

Debra's Super Tip

Your bra should be a top fit when on the outermost hook. That way – as your bra loosens over time, you can tighten the band using the inwards hooks. If you must go down a cup size, go up a band size. If you must go up a cup size, go down a band size. Now you're bra smart. Knowing and not guessing your size means no more sore boobs, shoulders, or back, and you can confidently adjust to changes in your body and breasts.
