The Most Common Mistakes People Make When Choosing A Bra Size

Whether it’s relying on outdated measurements or choosing a style that doesn’t suit their body, there are several common mistakes people make when selecting a bra. We demystify the bra selection process to help you choose a bra that’s perfect for you!

Finding the perfect bra size can be more challenging than it seems. Many people wear the wrong bra size without even realising it, leading to discomfort, poor support, and an unflattering fit. But what are the right ways to find a bra?

Keep reading for 8 common mistakes (and what to do instead), so you can find the perfect bra that feels amazing whilst offering the right level of support.

#1 – Relying on Old Measurements

One of the biggest mistakes people make is assuming their bra size never changes. Factors like weight fluctuations, pregnancy, ageing, and hormonal shifts can all affect breast size and shape. If it’s been years since you last measured yourself, there’s a good chance your size has changed. A professional fitting or measuring yourself at home using a soft tape measure can make a huge difference in finding the right fit.

#2 – Choosing the Wrong Cup Size

Many people mistakenly assume that a bigger cup size means a bra is larger overall, or that a smaller cup size will offer better support. In reality, cup size is relative to the band size. A common issue is wearing a band that’s too big and a cup that’s too small, leading to spillage, gaping, or an unbalanced look. This is especially important when selecting styles like push up bras, which rely on proper fit to enhance shape and provide lift without causing discomfort.

#3 – Ignoring the Band Fit

The band is responsible for most of a bra’s support, yet many people focus too much on the straps. A band that’s too loose won’t offer adequate support, causing the straps to do more work than they should. On the other hand, a band that’s too tight can dig in and cause discomfort. A well-fitting band should sit level across your back and be snug but not restrictive. You should be able to fit two fingers under the band comfortably, but if you can pull it away more than a few centimetres, it’s likely too big.

#4 – Not Adjusting the Straps Properly

Bra straps should provide gentle support without digging into your shoulders or constantly slipping down. If the straps are too tight, they can cause discomfort and leave marks on your skin. If they’re too loose, they won’t offer enough lift, making the bra feel unsupportive. Regularly adjusting the straps ensures a comfortable fit, especially since elastic can stretch over time.

#5 – Sticking to One Size Across All Brands

Bra sizing isn’t universal. A 12C in one brand might fit completely differently from a 12C in another. This is because different brands use varying sizing charts, materials, and construction methods. Instead of assuming your size will always be the same, check the brand’s size guide or try on a few sizes to find the best fit.

#6 – Not Considering Breast Shape

Breast shape is just as important as size when choosing a bra. Some styles work better for certain shapes than others. For example, full-coverage bras are great for fuller busts, while balconette styles suit those with more rounded breasts. If a bra doesn’t sit smoothly against your chest, gaps at the top of the cup or spillage at the sides might indicate that the style isn’t the best match for your shape.

#7 – Wearing a Bra That’s Past Its Best

Even the best-fitting bra won’t last forever. Over time, the elastic stretches, the fabric wears down, and the support weakens. If your bra no longer feels as supportive as it once did, or if the band rides up your back even on the tightest hook, it might be time for a replacement. Rotating between multiple bras can help extend their lifespan.

#8 – Not Trying Different Styles

Many people stick to one type of bra simply because they’re used to it, but not all bras suit every outfit or occasion. A supportive sports bra is essential for exercise, while a seamless T-shirt bra creates a smooth look under fitted clothing. Trying different styles ensures you have options that match both your wardrobe and your comfort needs.

Final thoughts

A well-fitting bra can make a big difference in how you feel throughout the day. Avoiding these common mistakes can lead to better support, improved comfort, and a more flattering fit. Taking the time to find the right size and style for your body is worth the effort and can enhance your confidence as well as your overall well-being.
