Hi there I hope this helps. This is a similar answer to one I provided to another women recently: Predicting cup size in a breast reduction consultation is a common concern for many women seeking this procedure. However, it's essential to understand why accurately predicting cup size is not always feasible and why it shouldn't be the primary focus of the consultation. First and foremost, cup size is a notoriously unreliable measurement of breast size. The concept of cup sizes can vary significantly between different bra manufacturers and even between different styles within the same brand. Factors such as band size, breast shape, and individual body proportions all contribute to how a bra fits and what cup size it corresponds to. Therefore, basing expectations solely on achieving a specific cup size can lead to disappointment and unrealistic goals. During a breast reduction consultation, the focus should instead be on discussing your goals, concerns, and desired outcomes. A skilled and experienced plastic surgeon will assess factors such as breast volume, symmetry, nipple position, and overall breast shape to develop a personalized surgical plan that addresses the patient's unique needs. This plan may include removing excess breast tissue, reshaping the breasts, and repositioning the nipples to achieve a more proportionate and aesthetically pleasing result. A good rule of thumb is that the breasts will be reduced by about half of their current size in a breast reduction. Some patient will say that is too much, others will say that is too little. It is helpful when trying to figure out whether someone is looking for a reduction or a lift. However in general this approach leaves enough tissue to recreate a pleasing aesthetic and keep the breast size harmonious with the rest of the body as we mature. Now no 2 patients are alike, but that is why this is simply a rule of thumb. Additionally, predicting cup size after breast reduction surgery is further complicated by the fact that breast size can change over time due to factors such as weight fluctuations, hormonal changes, and pregnancy. While the goal of breast reduction surgery is to create long-lasting results, it's important to recognize that individual outcomes can vary, and some degree of unpredictability is inherent in any surgical procedure. In your case you should wait 6 months after completion of breast feeding to get an accurate reading of the volume of your breasts. Again variable but many women will deflate further. Instead of focusing on cup size, focus on communicating your desired aesthetic outcome and trusting the surgeon's expertise to achieve the best possible results. Make sure you connect well, look at their before and afters, and see if you like their aesthetic. By approaching the consultation with realistic expectations and a collaborative mindset, you can work together with your surgeon to create a surgical plan that aligns with your goals and delivers a satisfying outcome that enhances both physical appearance and your quality of life.
