12 Bra Myths You’ve Probably Believed All Your Life

Many of us have the typical love-hate relationship with our bras. We appreciate the support and the way they make the girls sit up nice and perky, but we also count down the hours everyday until we can slip that booby chamber off through our shirt sleeve and fling it across the room.

Bras have been around in some form or another for hundreds of years and there are more myths about wearing them (how they affect your health, sagging, etc.) than we can count, but these are just a few you should probably stop believing right now.

1. Not wearing a bra will make your breasts sag.

Many women are under the impression that not wearing a bra can cause saggy breasts. This is however, not true. Not wearing a bra only brings your breasts to their original shape and does not initiate sagging although it might seem like that.

2. Sleeping in a bra stops your boobs from growing.

Tbh, when I first started wearing a bra I got in the habit of wearing it to bed every night. That was until someone told me that sleeping in your bra is bad for you and stops your boobs from growing. Fortunately, this is not true. According to Dr. Amber Guth, who works at Breast Cancer Surgery Multidisciplinary Fellowship there are no medical findings to support this. “There is certainly no evidence that sleeping in bras is either helpful or harmful,” Guth said.

3. You can wear training bras for bigger boobs.

I’ve definitely heard this one before and never thought there was much truth to it, but in case you are under the impression that it works, please know this could not be more inaccurate. Training bras and/or sports bras are designed for your comfort and have nothing to do with breast size. They don’t initiate breast enlargement in any way. So if that’s why you are sporting one, don’t bother.

4. They should be fastened on the tightest hook.


Again, false. “A bra is going to stretch about three inches in its lifetime,” bra fitting extraordinaire Bobbie Smith told Huffington Post, and when it does, “that’s when you go to the next set of hooks.” It makes more sense to invest in a bra that fits well on the last set of hooks and then, when it begins to stretch you can use the tighter ones.

5. Your cup size is more important than band size.

In case you didn’t already know, it’s not the bra’s underwire nor the straps that do the heavy lifting. It’s actually the band that’s holding everything together, which is why it’s so important to find a bra that fits your current bust measurements.

6. Underwire bras increase cancer risk.

This is yet another myth that has no evidence to back up its claims. According to the Scientific American, the theory was brought to light by a pair of medical anthropologists who claimed that “by inhibiting lymphatic drainage, bras trapped toxins in the breast tissue, which caused cancer.” Critics insist that there is a lack of sufficient evidence to support this claim.

7. The lightest bra is the least visible.


Though this may seem obvious to some, many people choose white as their color of seemingly least noticeable bra. Most women think wearing a white bra under a white shirt makes your bra invisible, but this isn’t true. A skin toned bra is definitely your best option.

8. You should use Woolite to wash your bras.

Woolite and other detergents like it are supposedly ideal for washing bras, but this is actually a big no-no. Bra-fitting specialist Bobbie Smith says “it was actually designed to soften wool, so you shouldn’t use that on elastic, because you want the elastic to stay firm.” Good to know, Bobbie.

9. Bras have uniform sizing.

This one is almost laughable. Any woman who has ever worn a bra knows that uniform sizing is a joke. Buying a 34B from Target vs Victoria’s Secret is a whole different ball game. Author of The Bra Book, Jene Luciani insists that “each brand has their own ‘fit model’. Plus, you can be a different size for several styles within the same brand.” Men will never know the struggle.

10. They should only be washed once a week.

Well, this has been my motto for pretty much forever. Unfortunately, it’s not necessarily true. In fact, “the dirt and oil in our skin can break down the elasticity of the bra,” explains Luciani. “So it’s best to wash as often as possible.” So maybe, once every couple of days?

11. A good bra can last a couple of years.

That sounds accurate right? If only. Imagine all the money we would save. However, most experts agree that bras have a fairly short lifespan…6 to 9 months at the most. Looks like I need to do some serious closet purging.

12. There’s only one “right” way to put on a bra.


As if! The options are practically infinite. Clasp in the front and do the spin around, maybe slip it on one boob at a time, or slip it over your head already clasped. There is absolutely no singular “right” way to put on a bra. Just do your thing, who TF cares?
