Why Do Women Wear Bras? [Regular, Sports & Nursing]

There are lots of ideas on this subject of why women wear bras. Some people say it’s for comfort, while others say it can prevent sagging. 

I’ve also heard friends suggest it’s best to wear a bra to bed, and the opinions go on and on. Eventually, it really makes you wonder, “what then is the truth?”

First, let’s erase the idea that we don’t need bras at all, since you cannot show up at work with your lady parts stealing all the attention in the room.

Now that we’re all clear, I’ll explain why women wear bras and demystify the misconceptions. 

Let’s get started.

Should women wear bras?

Yes, they should. 

Wearing a bra can help support the breasts and prevent back pain. It can also protect the breasts from sagging or bouncing during physical activity. Additionally, it can provide a layer of warmth during cold weather.

I know that some women feel more comfortable and confident wearing a bra, while others do not. Here’s my advice, do what works best for you.

Benefits of wearing a bra

why do women wear bras

From an adolescent age, you’ve probably been told to wear a bra and never cared much to know the real reasons why. Here’s your lucky day, and below are the main benefits of this undergarment.

1. Comfort

Bras can make women feel more comfortable by providing support for the breasts and alleviating some of the aches and pains that can come from having large breasts.

2. Posture

Wearing a well-fitting bra can help improve a woman’s posture by ensuring that her breasts are properly supported.

Large breasts can cause posture problems, but a well-fitting bra can help to alleviate these issues.

3. Protection

Bras can protect the breasts from damage caused by impact during exercise or from sagging over time. It can also help to relieve pain in the breasts caused by activities like jogging or other high-impact exercises.

4. Appearance

Bras can help create a more polished and put-together look, particularly under clothing.

By lifting the breasts and giving them a more rounded shape, bras can help clothes to fit and look better on women of all sizes.

5. Confidence

Feeling good about oneself can be a confidence boost, and wearing a bra that fits well and makes you feel comfortable can contribute to this.

6. Support breast tissue

Bras can help to prevent sagging, create a more flattering silhouette and keep the breast tissue healthy.

Benefits of not wearing a bra

There are a few benefits of not wearing a bra that you may not have considered.


For starters, it can actually be more comfortable not to wear a bra. That is because bras often constrict the chest and cause discomfort, especially during physical activity. 

In addition, not wearing a bra allows your skin to breathe, which can help prevent skin irritations. And if you often sweat a lot while wearing your bra, it could trap moisture and make you feel uncomfortable.


Not wearing a bra can also help improve your posture since you’re not constantly pulling your shoulders back to adjust your straps. 

Also, if your bra is always too tight, it can affect your posture over time.


Some women believe that ditching the bra can save money in the long run, as bras are a costly and often ‘unnecessary’ garment.

These benefits are valid and worth considering.

Benefits of wearing a bra to bed

Wearing a bra to bed can help to support your breasts and prevent them from sagging. It can also make you feel more comfortable and help to reduce the appearance of stretch marks.

If you feel pain in your boobs towards the time of your menstrual cycle, it’s also good to wear a regular bra to bed. It can help cushion your boobs and provide relief throughout the night.

Also, if you are pregnant or nursing, wearing a nursing bra to bed can help to support your breasts and prevent them from leaking. And you’ll end up sleeping better.

That said, wearing a bra to bed should not be an everyday thing because it can constrict blood flow below your boobs if it’s too tight. And it’ll ultimately hurt your breast tissue over time.

Do you have to wear a bra to work?

Yes, you should, but it also depends on your type of work.

Wearing a bra can make you feel more confident and professional. And you will avoid any potential wardrobe malfunctions or discomfort.

If you are not used to wearing a bra, start by wearing one with padding or an underwire for extra support. You can also try different styles of bras to see what is most comfortable for you. The choice of wearing a bra also depends on the dress code of your workplace.

Regular bra vs sports bra

Many women are unsure about whether they should be wearing a regular bra or a sports bra when exercising.

There are benefits to both types of bras, and the best option for you may depend on the type of exercise you are doing.

Benefits of regular bras for exercise

  • Regular bras offer more support than sports bras, which can be beneficial for women with larger breasts.
  • Regular bras can also be more comfortable for women who are not used to wearing sports bras.

Benefits of sports bras for exercise

  • Sports bras are designed to provide support and minimize breast movement during exercise. This can help reduce discomfort and prevent chafing.
  • Sports bras can also be more comfortable for women who sweat a lot during exercise.

So, what type of bra should you wear when exercising? If you are doing a high-impact activity, such as running or jumping, a sports bra is a good option.

If it’s a low-impact activity, such as walking or yoga, a regular bra may be more comfortable. More importantly, choose the bra you feel most comfortable in.

Regular bra vs nursing bra

There are a few key differences between regular bras and nursing bras. First, nursing bras usually have cups that mothers can open or pull down to allow easy access for breastfeeding.

They offer extra support around the band and straps to provide more comfort and lift.

Also, many nursing bras come with a clip or hook-and-eye closure at the front. This makes them easier to put on, take off and adjust as the body changes during pregnancy and nursing.

Conversely, regular bras have less fabric and padding and are not meant to be pulled down for nursing. They offer less support around the band and straps, which can be uncomfortable for some women during pregnancy and nursing.

In addition, most regular bras have a traditional hook-and-eye closure at the back, which can be hard to reach when you’re pregnant or nursing.

Does wearing a bra affect milk supply?

It’s unlikely.

It is a common misconception that wearing a bra will decrease milk supply, but there is no evidence to support this claim.

However, it is important to note that if you wear a very tight bra that compresses your breast, it can lead to constricted milk ducts.

How to know if a girl is not wearing a bra

There are a few telltale signs that you can look for to determine if a girl is not wearing a bra.

  • First, take a look at her posture. If she is standing up straight with her shoulders back, then it is likely that she is not wearing a bra.
  • Another sign to look for is if her nipples are visible through her clothing. If yes, then it is likely that she is not wearing a bra.
  • Finally, take a look at her chest to see if there are any visible lines or indentations where a bra would normally sit.

How long should you wear a bra in a day?

At least 8 hours per day.

This will also depend on other factors, like the type of bra you are wearing, your comfort, and your activity level.

If you are engaged in strenuous activity or particularly sensitive to discomfort, you may need to adjust this number accordingly. Listen to what your body needs and make sure you are as comfortable as possible.

Does not wearing a bra cause sagging?

Not entirely.

As many factors can contribute to sagging breasts. Not wearing a bra can help to prevent sagging, as the supportive undergarments can weaken the breast tissue over time.

Genetics also plays a large role in breast sagging, so even if you do everything right, you may still end up with droopy breasts. 

Another way to avoid sagging breasts is to maintain a healthy weight, as being overweight or obese can put unnecessary strain on the connective tissue and lead to drooping.

What is the actual purpose of a bra?

To support the structure of your boobs and their weight. While bras are necessary, avoid tight brands as they’ll only put a strain on your back.
