Will sports bra stretch over time?
How do you know what size to get in a sports bra? – If you can pull the strap of your sports bra up high enough that it can touch your earlobe, it’s too big. Try on the next size down. And remember if it initially feels too tight, they do stretch. To get longevity from your sports bra you’re best to go for the tighter fit (as long as it’s not uncomfortably tight) and let it loosen up over time.
Are sports bras supposed to be tight?
80% of women wear the wrong bra size, but it doesn’t have to be this way. From support, to fitting and construction – here’s what you need to know to pick the best sports bra for you. The unique motion of running causes your breasts to move in a figure of eight motion, sometimes up and down as much eight inches.
- This puts your Cooper’s ligaments – the thin collections of connective tissues that help support your breasts – under huge strain.
- Without the correct support, you’re likely to experience soreness and could cause lasting damage.
- Sports scientists from the University of Portsmouth studied how breast tissue is damaged when running, in regular bras and a variety of sports bras.
They found low to medium impact sports bras reduce bounce but are not effective for restricting the side-to-side movement that occurs when running. In fact, their research shows that women change the way they run depending on the type of bra worn. So not only will a good sports bra provide you with vital support, it could help you to set a new PB too.
- Sports bras offer three different levels of support: low, medium, and high impact.
- The type you need depends on your cup size and the type of exercise you do.
- Low impact activities: Walking, yoga, strength training.
- Medium impact activities: Dancing, skiing, cycling.
- Construction: Low-medium impact sports bras typically feature a cup-less design and restrict movement by compressing the breasts tightly against the chest wall.
High impact activities: Running, aerobics, mountain biking. Construction: High impact bras are made with a defined cup structure – akin to regular bras – to encapsulate and support each breast. Some high impact bras will use a combination of both encapsulation and compression methods to maximise support.

Step 3: Bust measurement: Measure around the fullest part of your breast. Again, the tape measure should be snug but not so tight that it restricts breathing. Step 4: Subtract your rib cage measurement from your bust measurement. The difference is your cup size. If you’re in between sizes, round up.

An alternative to steps 3 and 4: Try a few different cup sizes for fit. Cups should fit without gaps or wrinkles, they should feel snug and secure but shouldn’t be so tight that your breasts spill out the side or over the top of them. Step 5: Use our size charts to identify the right size sports bra for you.
Even once you have you have your measurements, finding the right sports bra can be tricky and usually requires you to try a few different sizes and brands. Here are some tips for getting the perfect fit Snug, but not too tight: A sports bra should fit tighter than a regular bra but shouldn’t restrict breathing; you should be able to fit two fingers between the straps and your shoulders.
Wrinkles are bad: The fabric of the cup should be smooth. Wrinkles in the fabric are usually an indication that the cup is too big. Conversely, if you’re spilling out of the cup, it’s too small. Watch out for gaps: Any underwire should lay flat against the rib case, below your breast tissue, and should not pinch or dig in.
Adjust the straps: Raise your hands up over your head. If the band rides up it’s usually a sign it’s too big, though it is possible that the straps or the back closure may need adjusting. Move around: Before buying your bra, jump around and swing your arms – (it’s probably best to do this in the changing rooms or somewhere else other people can’t see you).
If you experience pain or discomfort, then try another sports bra. If in doubt, visit your nearest Runners Need store for a free bra fitting service. A sports bra will last around 30-40 washes, but the technical fabric will loosen with each cycle, making it less effective.

“The band around the body determines how much support your bust gets from the bra”‘ The band needs to fit quite tightly around the body, which is why it’s always made from an elastic material with a small amount of added elastane. The material between the cups on the other hand is firm to hold the cups in place.

Your bra straps falling down can actually mean a few different things! Firstly – they might just need tightening up! The adjusters will natually start to loosen over time when you are wearing and washing your bra.

- Secondly – Your underband may be too loose! Yes – everything’s connected! If the underband is already too loose on your body, the bra straps will then automatically be set too wide or far apart on your shoulders.

Drying your Sports Bra – The best option is to dry your sports bra flat in the shade. A good option is on a towel. If you do opt to line dry it’s better to hang from the centre of a cupped sports bra, or by the base of a crop top style, rather than the straps.
This prevents the straps getting stretched out by the wet sports bra pulling downwards. Avoid pegs as they can damage delicate fabrics. Avoid drying in full sunlight as this can cause fading and the breaking down of fibres. If you have washed your bra in the shower, hang it over the shower rod or tap from the centre of the bra cups and leave to dry.
Do not tumble dry as the elasticity and fibres will deteriorate with heat altering the integrity of your bra. Shrinking of the fabrics can also occur which can cause your sports bras to become misshapen, not to mention alter the fit and comfort of the bra.
