Thank you for your question. In the early recovery period I would not recommend push up bras but once cleared to resume underwire and other bra use, they do not pose a risk to your implants or breasts. It is important that after any augmentation that you use good supportive garments to help limit future sagging. Hope this helps.
You have raised a very common question! Once you have been cleared to wear push up bras then its perfectly fine to wear them without any adverse affects. If you find the underwire irritating then you can always make a small incision and remove the underwire.
