Sleep Bras For Big Breasts

A sleep bra, sometimes called a night bra, or comfort bras; is a boon for many women with big breasts. For some it is only used when their boobs swell and become uncomfortable during pregnancy; but for many women with a large bust 'gently' supportive big bras at night are an absolute blessing.

Comfortable bras for large busted women is always a priority and it may or may not surprise you that many women like to wear these as comfort bras around the house, for doing the housework or just casual use. Not to go out in but a simple comfortable alternative for ladies who like to 'free themselves up' a little occasionally especially in a non-wired alternative.

Again, most of the bras shown here are simply lifted from Amazon and can be found by clicking the picture itself, if you are interested but this is no hard sell, it is purely your choice.

A minor concern was raised that it might be harmful but that was mainly to do with wearing the same day time bra at night too. There is no real scientific evidence to support a theory that a sleep bra does you either harm or good so it really comes down to personal choice.

You can wear a 'normal' bra to bed but it is not advisable as they tend to be too tight, the underwiring digs in as you lay on one spot for hours at a time and they are not comfortable. Remember also they are designed for a vertical stance and regular movement.

The fact is most nightwear, be it pajamas, a tee shirt or a nightie, does not have any support. For most women with 'normal' busts, this is not a concern but for women with a large bust this can be a real issue.

Why Wear A Comfort Bra At Night?

You may never have considered it but a night bra for big breasts can be a help. There are a number of reasons why women wear them but the principal reasons are:

  • Lack of comfort at night due to the weight of the breasts
  • Pain when boobs expand during pregnancy
  • Leakage whilst breast feeding requiring a support for pads
  • Discomfort during that time of the month
  • Recovering from surgery and you can only manage a gentle post op bra
  • Concerns over maintaining shape
  • Irritation from sensitive nipples rubbing against sheets or nightwear

How The Night Bra Design Differs

Unlike a sports bra or strapless brassiere, a bed-time bra is specifically designed to be comfortable and some are even called comfort bras. They are normally:

  • lightweight, 
  • have full coverage cups
  • have wide straps, 
  • are made of soft fabric 
  • have no or little wiring,
  • simple or no clasps / hooks 
  • and no fillers

Most brassieres are naturally designed for you whilst you are standing / sitting up. Gravity will obviously pull your breasts down in a vertical fashion and the design is all about countering that.

At night, when you are lying horizontal on your back or side your boobs will settle out towards the sides so there is some specific design consideration for this.

Do You Need a Sleep Bra If
You Have Big Breasts?

I read an interesting source of opinions from doctors on this (www.realself.com) and the bottom line was that whilst there is a lot of strong opinions and anecdotal comment there is no conclusive scientific evidence of either the good or harm of wearing a bra at night. Most however advise against underwiring.

You may not 'need' to wear a sleep bra but you may well find it more comfortable. I for one value a good night's sleep above almost all things and anything that helps you achieve that, certainly gets my vote. It is a free country and the 'let-them-swing-police' will not see you in the privacy of your bed.

The main thrust of the anti-sleep bra opinion is aimed at under-wiring and being too tight thereby restricting circulation. This tends to be aimed at 'ordinary' brassieres, whereas most sleep bras are very light, have no wiring and are considerably less tight. Sleep bras are also often have a higher cotton content than 'normal' bras.

There is a school of thought that says you have natural support which is more than sufficient and you were designed that way so logically it must be good enough. That line of thinking ignores swollen and sore breasts from pregnancy, breast-feeding, menstruation, surgery or plain painful breasts, what ever their size.

It also ignores the scientific fact that big breasts are heavy and have a greater gravitational pull than smaller boobs so there may well be a very different requirement. Even if it is a different horizontal pull when sleeping, as opposed to our normal vertical posture, gravity does not stop working at night.

Night Bras

If you need or prefer support for your breasts at night, then investigate a night bra for a big bust. It is clearly not the same support but anything that helps 'the girls' cannot be bad and earns it's moniker the comfort bra.

Below is a selection of sleep bras for you to peruse at your leisure. They are a variety of makes, styles and prices. Hover your mouse over the pictures to expand them.


Odd Facts:

  • Whilst sleep bras sometime come in normal sizes, it seems odd at first to find that they can also be labelled simply: small, medium, large.
  • They are also known as comfort bras for the the somewhat obvious reason that they are very comfortable and women with breasts that are uncomforatble, for whatever reason, find great comfort there.
  • Similarly, many women will wear this as a post op bra. Clearly that is a time when you need support but your breasts are very tender. This is a perfect solution.
  • I read that (British TV presenter) Mariella Frostrup always wears a brassiere in bed, following advice from Paula Yates, in lieu of having surgery to ensure her breasts remain perky.
  • Marilyn Monroe also apparently slept in a bra to sustain her perkiness.

Alternatives To Sleep Bras
For The Big Busted:

Ignoring 'daytime' bras, the main alternatives are:

  • Sports bras. I must admit I was surprised at the amount of anecdotal evidence (on the internet) of big boobed women using looser sports bras for night wear.
  • Sleep Tank tops / Camisoles with built in support - see cami bras
  • Nighties with in built 'bras' - which is what I personally sometimes wear
  • Not an actual alternative but again I was interested to see how many women state they tuck a fluffy sock, flannel (or cotton equivalent) in the cleavage to keep the 'girls' apart.

Did you like this page, did you learn something, maybe it reinforced you own views? I want to give as much (hopefully helpful) advice to the busty sisterhood as I can.

Please remember, we are all different. You may like to wear certain clothes and styles which I am suggesting that you should not. That is your absolute right. Do what makes you feel good. This site undeniably goes for the more modest approach because I feel all busty ladies already know how to be more racy if they wish.

It would really help me improve the site profile if you would click the Facebook 'Like' button. Pretty please! Susan

Post Op Bras

Any woman who has been through surgery on or around her breasts needs a lot of care and time to recover.

These are known as comfort bras for a reason and are recommended by doctors as post op bras when the scar tissue is still too painful to wear a 'normal' brassiere.

And if there are any women recovering from surgery, my thoughts are with you. Hang in there girl!

Or should that be let the girls hang in there?


Something that is not easy for any woman but you do need to know how the back of the bra is sitting

Remember to check the back!
