The best sleep bras are there to offer your bust support throughout the night. Molding to your shape but also allowing for freedom of movement. 

Nothing makes us feel more ready to face the day than a good night's sleep and if you've already bagged yourself the best pajamas and formulated a bedtime routine, then you're well on your way to getting ready for bed. But if you find your bust is causing you discomfort at bedtime you might want to consider a sleep bra. 

While the need for purchasing the best bras to support our busts in the daytime is obvious, have you ever thought about the level of support your breasts need at night? Depending on whether you're after the best bras for small busts or the best bras for large busts, the level of support you'll need throughout the day is different. But just because we're horizontal at night, that doesn't mean our busts don't need a little help to ensure they sit in the best position. Not just a good foundation, bras are important for your overall back and breast health. At night, large busts, in particular, may find a sleep bra helpful to aid in a comfortable night's sleep. 

What is a sleep bra?

A sleep bra is a bra designed specifically for sleeping in. Unlike your regular bra, which is designed for uplift under clothes, a sleep bra is there to stop discomfort during the night. A sleep bra is different from your regular bra, even if you have one of the most comfortable bras. Bras for the day are likely to be tighter for support and shape, whereas a sleep bra will be closer to a bralette, in terms of fit and more like something you might own already simply for lounging in. This is because anything too tight or with an underwire will not only dig in but could affect circulation. 

What to look for in the best sleep bras

Not all bras that are good for sleeping in are marked specifically as 'sleep bras'. Bras that work for this activity hold certain characteristics or are constructed in a particular way to ensure they mold and sit flat on your body, offering the right support for a restful night. There are some dedicated sleep bras out there but knowing what to look for will help widen your options. 

When selecting the best sleep bra, there are a few important things to consider:

  • Wire-free—wires will be too constricting at night and can dig in. They also can cause tightness and marks. So always opt for a sleep bra without wires.
  • Seam-free—most sleep bras or sleep-appropriate bras will not have seams as these again can dig in, run or leave marks. You might see sleep bras with seams if they offer particularly high support for very large busts. 
  • Free from padding, or removable padding—if you usually wear a padded bra in the day, at night, you don't need the extra boost. Padding also adds bulk to a bra which can make it more difficult to sleep in. While you can choose a bralette style to sleep in that has padding, just make sure it can be removed.
  • Breathable—look for natural breathable fabrics, or high-tech fabrics that list breathable as a quality to ensure you don't feel too warm. 
  • Sweat-wicking—a nice added extra, sweat-wicking fabrics will keep you dry and are particularly handy in the warmer months. 

Who is a sleep bra for?

Anyone can invest in a sleep bra, but those with a larger bust will find a sleep bra most useful. If you have a bigger bust you may find that sleep can be uncomfortable because your breasts will move during the night. If this is an issue you are suffering from, then investing in one of the best sleep bras could help you get a better night's sleep.

Conflicting size information

The sizing information on the bra is rather conflicting as it suggests it fits up to a 34. However they fit up to a DD cup, and customer comments, although happy with the product suggest you need to size up to get a good fit. Listed as sleep tops rather than bras, they're made of soft, tubular knitted fabric with an attractive mesh yoke, making these a little sexier than your average sleep bra. Conveniently sold as a two-pack, offering you more for your money.

What are the benefits of a sleep bra?

  • Alleviate back pain —if you find that your breasts hurt your back, then you'll already have invested in some of the best bras for the daytime. For some women, particularly those with larger busts, a bad back from the result of a heavy bust can also impact their sleep. If that sounds like an issue you're experiencing, try a sleep bra to improve the position and support your breasts get at bedtime. Any continued issues should be discussed with your doctor. 
  • Help with sensitivity—for those with particularly sensitive breasts or nipples, a sleep bra can help to diminish some of these symptoms, particularly if you find how you sleep or your pajamas are irritating you. If sensitivity is an issue, however, consult a medical professional as well. 
  • Support—Mainly an issue for those with a larger bust, the skin tissue can strain during the night if your bust isn't supported. A sleep bra will help to position and hold your bust as you enjoy a good night's sleep.
