How Often Should You Change Your Bra?

By: Heather Bien

Wondering if your bra-changing habits might need a little tweaking? If you have two bras in your rotation for the whole year or have been wearing the same everyday bra for four-and-a-half years, you might know that you should be changing your bras more often, but just aren’t sure what the best timeline is. 

If so, you’ve come to the right place.

Here, we’ll answer all the everyday bra-changing questions you’ve wanted to ask, including how often you should change your bra, how often you should wash your bra, and when you should replace your bras with new ones. 

Should You Change Your Bra Every Day?

The short answer—it depends. Unless you’re regularly breaking into a sweat, you don’t need to change your regular bra every day. A change twice a week (or at least once a week) is a good guideline to aim for. However, breaking into a sweat isn’t the only thing that should prompt you to change bras. 

While regular bra-changing isn’t a science, dermatologist Alok Vij recommends switching bras every 2 to 3 “wears,” with a “wear” being when the old bra begins to:

  • Relax its shape
  • Accumulate noticeable amounts of ickiness

On average, this works out to switching bras once every 3 to 4 days (unless you’ve been through an extremely active day, in which case, you should put a new bra on right away). 

Changing your bra helps your skin stay healthy by removing dead skin cells, oil, and sweat residue from your body, but this isn’t the only benefit. One of the main benefits of wearing a bra and changing it often is that it helps them maintain their shape. 

The longer you wear a bra, the stretchier it becomes, so it’s a good idea to rotate bras regularly to ensure that the cups and straps retain their shape and elasticity. After all, you want to keep that flattering, well-fitted form as long as possible.

How Often Should You Wash Your Bra?

We all have our favorite bras. Maybe it’s the color, the texture, or even a memory we have about wearing it. But if we’re not careful, we could end up wearing that special bra for too long, resulting in a relaxed shape and a less-than-pleasant smell. 

So, after your 2 or 3 wears, remember to also wash your bra, rather than simply swap it with another. You may even need to wash more often depending on certain factors, including:

  • Where you live – Is your environment humid, or more dry and cool? Your immediate surroundings affect your bra’s longevity and should be a factor in deciding when to change or wash your lingerie. 
  • How much you sweat – We all have different lifestyles, with some leading to more sweaty moments than others. Being aware of how much and how often you sweat goes a long way to ensuring your bras (and by extension, your body) stay clean. Getting good bras to wear with tank tops or other workout apparel that have moisture-wicking properties would be ideal.
  • Your schedule – Washing bras every day—by hand, no less—might not be realistic for your situation. Find a routine that works for you and ensures your undies remain as clean and fresh as possible. 
  • What activities you do during the day – The condition of your bra depends on how and how much you move throughout the day. Take an account of your daily activities, and figure out how many “wears” a day would be for you. 

How Often Should You Replace Your Bras With New Ones?

Some of us might be holding onto bras we’ve been wearing for the past 3 years. If that’s your story, don’t worry—you’re not alone. It can be hard to let go of a favorite piece of lingerie you spent hours searching for and even longer lounging in. But all good things must come to an end, and bras—even the pretty ones—are no different. 

Here’s a good rule-of-thumb to remember: Replace your bras every 6 to 12 months. 

That’s a broad range, but it’s because many factors come into play when determining the right time to replace your bras, such as the number of bras you own and the frequency of your wears and washes.

Keep an eye out for these warning signs that indicate a bra should be replaced:

  • Cups are stretched out and no longer fit well
  • Cups are too small
  • Band is no longer snug and comfy
  • Little threads of elastic can be seen poking out
  • Straps are loose
  • Underwire pokes or digs at you
  • Fabric is frayed
  • Color is faded or splotchy around the straps

In any of these cases, it’s time for a new bra.

What is Organic Cotton?


What is Organic Cotton?

By: Heather Bien We’re all trying to be better stewards of Mother Earth. From recycling to upcycling and eating conscientiously to dressing mindfully, our choices affect the planet. So choosing organic cotton clothing seems like an easy decision, right? Not so fast! As with all sustainable choices, it’s important to take a moment to learn a bit more about why organic cotton might win over conventional cotton—and what makes these two materials different in the first place. Read on if you’re interested in learning about organic cotton and whether it’s the best choice for you and the environment. Conventional cotton Before we get into debating modern cotton farming techniques, let’s get familiar with the plant we’re talking about: cotton. It’s soft, durable, and probably on your body right now. But what else do you really know about cotton? Here are the basics: Cotton comes from the cotton plant – The cotton plant is a warm-season woody perennial shrub from the genus Gossypium and the family Malvaceae. Cotton fabric is made from the plant’s fibrous seed-hair (which is also called a cotton boll). Cotton is one of the top agricultural crops – Traditional cotton is the most widespread and profitable non-food crop in the world. Although the plant is capable of growing in any warm-weather climate, India and China are now the top producers of cotton globally. Cotton is thirsty – A normal cotton plant requires 10 gallons of water to reach peak potential. That doesn’t sound so bad, but multiplying it outward, that means it takes about 5,000 gallons of water to produce just 2.2 pounds of cotton fabric. Pests think it’s delicious – Not only is cotton thirsty, but it’s prone to pest infestations from bollworms, weevils, aphids, stink bugs, thrips, and spider mites. In order to combat these common pests, conventional cotton is routinely sprayed with a veritable salad-dressing of pesticides, many of which can remain in the soil and water supply for years afterward. Cotton harvesting requires defoliation – In order to quickly and efficiently harvest cotton, many commercial growers use chemical defoliants to strip the leaves from the cotton plant prior to harvesting the bolls. Like pesticides, these chemicals remain in the environment and on the cotton itself. Is organic cotton better? All of those cotton factoids point pretty compellingly to buying and wearing organic cotton fabric. But first, it’s important to understand what sets this organic alternative apart. Why exactly is “organic” cotton anyway? You might associate the word organic with your healthy fruits and veggies, but it’s not always clear what this term means when it comes to cotton. For many years, there was not a standard definition, but today, the United States Department of Agriculture (USDA) and Federal Trade Commission (FTC) require that any cotton product labeled “organic” meet the following criteria: Made with fibers from USDA-certified organic crops Third-party certified (ie., through the Global Organic Textile Standard) under the National Organic Program standards Has a specific percentage of organic material (depending on the crop) But this definition is a little circular, so we need also to define USDA-certified organic crops. According to the USDA, organic crop standards are defined as follows: Land must have had no prohibited substances applied to it for at least three years before the harvest of an organic crop. Soil fertility and crop nutrients will be managed through tillage and cultivation practices, crop rotations, and cover crops. These can be supplemented with animal and crop waste materials and allowed synthetic materials. Crop pests, weeds, and diseases will be controlled primarily through management practices, including physical, mechanical, and biological controls. When these practices are not sufficient, a biological, botanical, or synthetic substance approved for use on the National List may be used. Operations must use organic seeds and other planting stock when available. The use of genetic engineering, ionizing radiation, and sewage sludge is prohibited. What is organic cotton? In short, it’s cotton that is farmed according to these practices and certified organic by the USDA. Why should you choose organic cotton? With fewer pesticides, fewer synthetic chemicals, and more thoughtful cultivation practices, organic cotton can certainly offer a more environmentally friendly choice when compared to regular cotton. Is organic cotton sustainable?  Here are a few other reasons why organic cotton can be a better alternative for you and the earth: It’s better for our water resources – According to an analysis by the Textile Exchange, producing an organic cotton T-shirt requires 1,982 fewer gallons of water compared to a regular cotton T-shirt. Because organic cotton uses less chemicals, its production also releases fewer toxins into our aquatic ecosystems. It’s good for the soil (and our carbon footprint) – According to the Soil Association, the more natural cultivation practices and fewer pesticides used by organic cotton farmers can support healthier soil. That soil, in turn, can absorb more carbon from our atmosphere and help keep the planet healthy. It encourages biodiversity – Multiple studies have shown that organic farming practices can encourage more diversity among the animal species of our planet. Sustainability is sometimes in the eye of the beholder. But when it comes to plant-derived textiles, the ones which help us create a healthier world are always a better alternative.  Explore the benefits of bamboo with Boody Whether you choose to purchase conventional or organic cotton clothing, the fact that you are shopping mindfully for yourself is a win for the environment.
