Is this rippling at 3 months post-op? (Photos)

Without examining you it is difficult to be certain but it appears as though it is just some irregularity of the breast tissues that is being exaggerated a bit because of the implants. I don't see any rippling in the typical sense that we discuss it. If you are really concerned I'd suggest booking an appointment with your surgeon to be examined and reassured. Hope that helps! 

Hello! thank you for your question and providing pictures
It´s very difficult to make an evaluation only with pictures and the rippling is not that noticeable at least in the photos. Sometimes the tissues are very thin and we are able to feel the implant. It´s still very in your healing process so there might be some swelling, be sure to visit your plastic surgeon for follow up, congratulations your result looks very good. Keep taking care of yourself and don´t worry I think you are going to be fine.
Wish you the best
