Thank you for your question. Based on your photos, you appear to have a nice starting place and should have a nice result with breast augmentation surgery. Unfortunately, predicting a cup size is not possible. A rough estimation would be going up one cup size for every 150-200cc. The most important factor when sizing implants, is working closely with your surgeon in person to find the implant size that gives you the look that you desire. Careful measurements of your breast and chest wall will help determine which size implants will fit within your natural breast footprint. Taking into account your desired look, and your measurements, an implant is chosen that specifically fits your body. Unfortunately, online recommendations are not that helpful. Make sure that you have a good relationship with your plastic surgeon, so that you two can work together to find the right size. In my office, patients try on implants in a bra and clothing. There able to see how they look in the mirror, and in photographs. Women are also encouraged to bring in wish pictures, so that I can get a sense of the look that they would like to achieve. Good luck with the process!
