You should wear the surgical bra day and night until Dr. Jugenburg advises otherwise; this is dependent on your healing and is typically until 2 - 4 weeks after surgery. We advise patients to wait to purchase new bras until 1 month after surgery, so that the sizing is accurate after any swelling has resolved and the implants have settled. If you wish to purchase one or two bras for the time period between wearing your surgical bra and the final fitting, be aware that your bra size may be less accurate at this point.
