How Soon After a Breast Lift and Implants Can You Go Without a Bra?

This truly depends on what is being performed. In some instances you can go without a bra immediately if this is acceptable to the surgeon. In my practice, I commonly allow patients to go without a bra after 72 hours.

I do no think the brea does anything. The only reason why I have patients wear one is to keep loose gauze inside just in case of oozing or staining.

Regarding  "How soon after a breast lift and implants can you go without a bra?" 

Since your healing will not be complete for up to 4 months and the tensile strength of the scar will never match that of non-operated skin, when would you feel lucky enough to test your wound healing against gravity and the bounce of your new breast implants?

Breast maintain their attractive shape when they are supported as much as possible. If they are not they sag and operated breasts will sag faster.

So as regards your "are we there yet?" question, I would refer you to your surgeon but keep asking yourself - how lucky do you feel and how much of a chance do you want to take?
