Ivanka Trump sporting what appears to be a new set of breast implants. Although they look a bit big for her body, there is a possibility that they will decrease in size over the next few months. Her breasts look a bit swollen in the upper pole (the upper part of the breast). This is very common in breast augmentation where the implant is placed under the chest muscle. It can take several months for the implants to settle or drop, after which they will look smaller and more natural.
When breast implants are placed above the muscle, the swelling is less and the upper pole swelling is less as well. I would bet that over the next few months her chest will look better and better.
