Am I sagging and am I a 34D? (Photo)

Hello, over time implants can descend lower than their original position, then the nipple looks relatively high on the breast mound.  This is called "bottoming out" - perhaps you are noticing this change over time.  Regarding your bra size, this is hard to determine from photos but you can have proper bra fitting to determine this.

Many thanks for posting your questionFist of all, it appears that your breast size is around a D cupHowever the issue that I see is one of bottoming out - it appears that your breast implants are sitting a bit low in the breast. Is this what you mean by sagging?If so, and it bothers you, then revision surgery might be required.The best thing would be to discuss with your plastic surgeonGood luck

It does appear that you are bottoming out.  You probably had smooth implant placed.  There are newer textured silicone implants that resist dropping like that.  I recommend you switch out.  You may need a breast lift as well during that procedure.

Thank you for your question and providing photos. Based on the photos provided it appears that your implants have inferior displacement. I would recommend you discuss this and your concerns with your surgeon. Best of luck

Thank you for your photographs and questions. I am sorry to hear about your disappointment with your breast augmentation surgery, but I can see your reason for concern.  It appears that your breast tissues have stretched with time causing your implants to settle too low on your chest, or bottom-out.  Unfortunately this can only be corrected with a revision surgery to tighten the breast pocket.  In order to help prevent this from occurring again you may want to consider reducing the size of your implants and/or using an internal bra for additional support. Talk to your surgeon about your concerns, they can help walk you through your options.
