A post-surgery bra includes an aperture appropriately sited to so that tubes from a boost-treatment device or drain implanted in a wearer of the bra protrude therethrough. The post-surgery bra includes a fixation element for immobilizing the tubes of the boost-treatment device that protrude through the aperture. In some embodiments, the post-surgery bra also includes a retaining ring, which is coupled to the bra below the breast cup nearest to the aperture and which is openable and closeable for engaging and securing a loop of material that extends from the collection bulb of the drain.
