What is the purpose of the surgical bra 24/7?

Wear of the bra is an important component of predictable healing after an augmentation.  While the regimen may vary, every plastic surgeon I know recommends use of a bra during the post-op period to ensure that the implants stay where we want them.

Thank you for your question. I am an advocate for the use of supportive bras after breast augmentation surgery.   In my opinion, the use of the supportive bra may help prevent breast implants from moving into the "paths of least resistance": down or out. Having said that, there is no “standard” when it comes to the use of specific bras or garments after breast surgery. In other words, different plastic surgeons may have different practices when it comes to postoperative dressings/bras.  
In my practice, patients wake up with a surgical bra in place. This surgical bra, although not attractive, is supportive and used for about one month after surgery (some of my patients have been known to burn the bra ASAP). Then, patients transition to a soft sports bra. Wired bras are used when breast implants have reached their “final position” and patients have full sensation along the breast skin. Generally, the longer I have been in practice, the more I appreciate the use of supportive bras for the first several months after breast augmentation and revisionary breast surgery. Best wishes.

Surgical bras are worn for support and comfort after surgery. You should talk to your surgeon about their  preferred specific recommendations. We all have different post op regimens, I  also have my patients wear supportive bras for 4-6 weeks post op. a compromise would be taking your support bra off at night so long as you are sleeping on your back but you must clear this with your surgeon
