Sports Bras 101: How to Choose One That Works for You

Finding the right sports bra is one of those things that sounds simple until you're standing in front of a wall of options wondering what the difference is.

Racerback, crop, high-impact, low-impact? And why does one feel amazing while another has you tugging at it mid-workout?

Don't worry, we've got you. Here's a guide to sports bra types, fits, colours and how to choose the right one for how you move.

Why a Good Sports Bra Matters

Think of of a good sports bra as the foundation of your gym outfit. The right one keeps you comfortable and supported, and it means you can focus on your workout rather than on adjusting your kit. The wrong one can leave you distracted, sore or reaching for the cover-up hoodie halfway through your session.

Everyone's body is different, so the "best" sports bra is the one that suits your body, your activity and your comfort preferences.

The Different Types of Sports Bra

Let's take a look at the main styles on offer.

  • Racerback. The straps come together at the back in a T or Y shape, which gives you freedom through the shoulders and arms. This makes racerbacks a popular choice for yoga, gym sessions and anything that involves reaching, pulling or pressing. Our Racerback Sports Bra is a great example. It has a flattering U-neckline, a cropped fit and a stylish open-back detail.
  • Crop top style. Longer in length and often worn on its own, this style works well for gym sessions, casual wear and summer outfits.
  • Compression bras. These hold everything close to the body, pressing it against the chest. Many people like this snug, secure feeling, especially for lower-impact activities.
  • Encapsulation bras. These have separate cups to support each breast individually. They're often chosen for higher-impact activities like running.
  • Wrap and strappy styles. These are more fashion-led, with eye-catching straps and cut-outs. They look great, and they're best suited to lower-impact workouts and everyday wear.

Match Your Bra to Your Workout

This is the bit most people forget. Different activities put different demands on a sports bra, so it's worth thinking about what you'll be doing.

  • Low-impact activities (yoga, pilates, stretching, walking): You can go for more style-led options with lighter support.
  • Medium-impact activities (gym sessions, cycling, general training, outdoor activities): Look for a supportive, snug fit that stays in place when you move. Our racerback bra is designed for yoga, running, gym sessions and outdoor activities.
  • High-impact activities (running, HIIT, jumping): Support really matters here. Choose a bra you know feels secure when you're bouncing around, and always test it out with a few jumps before committing.

Everyone's body and comfort needs are different, so if you're unsure how much support you need, try a bra in a low-stakes workout first and see how it feels.

Getting the Fit Right

A sports bra should feel snug and secure, but you should still be able to breathe comfortably. Here's a quick checklist:

  • The band should sit firmly and stay level. If it rides up at the back, it's probably too loose.
  • Nothing should dig in. Straps, band and neckline shouldn't leave painful marks.
  • No spilling or gaping. The fabric should lie smoothly against your body.
  • You should be able to move freely. Raise your arms, twist and squat. If it feels restrictive or slips, try another size.

Our Racerback Sports Bra has a cropped, body-hugging fit and comes in four sizes, from S to XL:

Size UK Size Bust Underbust
S UK 6–8 33 cm 31 cm
M UK 8–10 35 cm 33 cm
L UK 10–12 37 cm 35 cm
XL UK 12–14 39 cm 37 cm

Those bust measurements are taken flat across the fullest part, so double them for your full bust. Measure yourself first and check the full size guide on the product page before you order.

Let's Talk Fabric

You want something that feels soft, stretches with you and doesn't weigh you down. Our racerback bra is made from a stretch performance blend (89% polyester, 11% spandex) with a lightweight 230 g/m² feel. That gives you flexibility for movement and a comfortable, body-hugging fit.

It's also easy to look after. Machine wash at 30°C on a gentle cycle, don't bleach, and tumble dry low. Washing your sports bras gently helps them keep their shape for longer.

Choosing Your Colour

This is the fun bit! Gone are the days when sports bras only came in black or white. Here's how to think about colour:

  • Black is the classic. It goes with everything, it's easy to style, and it's a great wardrobe staple. Shop more in Black.
  • Blue is fresh and calm, and it looks great with grey or navy bottoms. Browse more in Blue.
  • Red adds a bold pop of energy. If you want a workout outfit that gives you a confidence boost, it's a brilliant choice. Explore Red.
  • Purple and dark purple are rich, a bit different and flattering on lots of skin tones.
  • Grey is a soft, neutral option that's easy to mix and match. See more Grey activewear.

Our racerback sports bra comes in six shades: blue, gray, purple, black, dark purple and red. If you can't decide, why not pick two? Wearing a favourite colour on a day you don't feel like training can make a surprising difference.

Styling Your Sports Bra

Sports bras are no longer just for the gym. Here are a few ways to wear yours:

  • At the gym: Pair it with leggings or shorts and you're good to go.
  • Layered: Wear it under a loose Quick-Dry Gym T-Shirt for a casual, comfortable look.
  • On the way home: Throw a gym hoodie over the top to stay warm after your workout.
  • For colder days: Add a jacket or a beanie for the journey there and back.
  • Off duty: Wear it as a crop top on holiday or in warm weather.

A Few Handy Tips Before You Buy

  1. Try before you commit to a long run. If possible, test your bra with a few star jumps or squats to see how it feels.
  2. Own a few. Rotating between bras helps them last longer and means you always have a clean one ready.
  3. Replace them when they wear out. If the elastic has stretched or the fit has gone slack, it's time for a new one.
  4. Wash with care. Follow the label to keep the stretch and shape.
  5. Prioritise comfort. If it doesn't feel good, you won't want to wear it, no matter how nice it looks.

Things To Remember Before Buying A Sports Bra

The best sports bra is one that fits well, feels comfortable and makes you feel good enough to get moving. Think about what you'll be doing, find a style and size that feels secure, then pick a colour you love.
