What Does Post-operation Bra Do to the New Breasts?

The bra is supposed to provide support and compression to help prevent implant displacement and swelling. If it's too tight you should find another one that is snug but a little looser (but not too loose.)

A bra provides support and compression for the breasts for the first eight weeks. It prevents your implants from being displaced and also can minimize swelling to some extent. If your bra is uncomfortable, please talk to your surgeon.
