Our team of Fit Stylists is here to help you find bras that feel like they were made for you. We’ve worked with thousands of women to find their perfect fit, so we’re sharing some of our best advice here.

It’s time to settle this debate once and for all: to wear or not to wear a bra to bed. When it comes to sleeping with a bra on, rumors abound. Some say it prevents sagging. (It doesn’t.) Others say it’s bad for your health. (It depends.) And Marilyn Monroe was reported to have slept in a bra every night. (Only Marilyn knows for sure.)

Before we begin to debunk bra-related myths, we say the most important factor to consider when deciding to wear a bra to bed is comfort. If you prefer wearing light support to sleep, choose a bra that’s soft and moves with you, like our Pima Cotton Wireless Bra. It’s seamless, wireless, and tagless for maximum comfort, so you don’t have to worry about it interrupting your slumber.

Is sleeping in your bra bad for your health?

The short answer: no, but it can be. To get a professional opinion, we spoke with Navya Mysore, MD, Medical Director at One Medical Group. Dr. Mysore explained that the connective tissue in breast tissue naturally loosens over time (aka sagging) which can be combatted by wearing a bra during the day. However, bedtime is a different story.

“At night, our breast tissue doesn’t have the gravitational pull as we are lying down, so we don’t need to wear a bra for prevention reasons,” she said.

Not only is it unnecessary, but sleeping in a bra that’s too tight can also cause the following issues, according to Dr. Mysore:

  • Skin irritation and indentations
  • Restricted breathing and blood flow
  • Worsened symptoms of acid reflux

That’s why it’s important to be sure you’re not wearing a bra that’s restrictive. To make sure your bra isn’t too tight, you should be able to slip two fingers between the band and your ribcage. Questions? Contact our expert team of Fit Stylists for help.

“Overall wearing a bra at night doesn’t help with preventing breast tissue from sagging and it can hinder in many ways, including reducing your sleep quality,” Dr. Mysore said. Moral of the story: let ‘em loose! Your breasts will thank you.
