Why Can't I Wear Under-wired Bras After Breast Augmentation?

We generally avoid using underwire bras for six to eight
weeks following breast augmentation for two reasons. With patients who have
undergone submuscluar placement of implants the pectoralis major muscle may
undergo spasm in the early postoperative period. This may force the implant in
an upward direction and lead to malposition. When this situation arises, we
utilize compression to force the implant in a downward direction. An underwire
bra would have the opposite effect.

Another reason for avoiding an underwire bra in the
immediate postoperative period is the potential for it to irritate a fresh
surgical incision. An inframammary incision would be directly under the
underwire and this might irritate the incision.

After six to eight weeks, wound healing and muscle spasm
should no longer be an issue. In most breast augmentation patients it’s
reasonable to resume the use of an underwire bra at this
time.

Thank you for your question. My patients will have a surgical bra that I place at the time of surgery. They normally wear this for the first week or two and then transition to a sports bra that opens in the front. By six weeks, if their implants have sufficiently descended, I let my patients know they can start wearing a normal bra (including a push-up bra). They may still undergo some changes which can change their bra preferences a few months later.

It is typical that surgeons advise patients to not wear underwire bras for the first few weeks of surgery. Of course, it really depends on the surgeon, though, so you should probably ask yours for their advice. I normally recommend patients don't wear an underwire bra for the first couple months because they can delay your healing, especially if you have incisions in the inframammary crease. You don't want any friction on your incisions which could be caused by an underwire bra.
