When considering breast augmentation, one of the most common and often confusing parts of the decision-making process is understanding the relationship between bra cup sizes and breast implant sizes. Many patients arrive at their consultation with a specific cup size in mind, hoping for a straightforward answer like “I want to be a C cup.” However, the truth is that the relationship between implant volume and bra cup size is not as simple or standardised as it may seem.
Miss Anca Breahna, Consultant Plastic and Reconstructive Surgeon based in Chester, UK, understands the concerns and questions that patients face when choosing the size of their breast implants. With extensive experience in both aesthetic and reconstructive breast surgery, she helps patients navigate these decisions with clarity, expertise, and empathy. Operating from Nuffield Health The Grosvenor Hospital in Chester and ASET Hospital in Liverpool, Miss Breahna offers a personalised, patient-first approach to breast surgery that ensures both safety and satisfaction.
This comprehensive guide will help you understand the difference between bra cup sizes and implant sizes, explain what factors influence the final outcome, and show how a thorough consultation with a skilled surgeon like Miss Anca Breahna can help you make the best decision for your body and lifestyle.
Bra cup sizes are often used as a way to describe breast size, but they are far from reliable when it comes to planning breast augmentation surgery. The first thing to understand is that bra sizes are not universal. Different lingerie brands use slightly different sizing systems, and the same cup size can fit very differently depending on the brand and the country of
origin.
Furthermore, cup size is always relative to band size. A 32C is not the same volume as a 36C. In fact, as the band size increases, the cup volume increases too. This means that two women wearing a C cup bra may have very different breast volumes.
This variation often leads to frustration when patients try to describe their goals in terms of cup size alone.
Many patients look to celebrities or social media influencers for inspiration, but what looks like a “full C cup” or a “DD” on one person may appear very different on another due to differences in height, frame, and chest width. The ideal outcome of breast augmentation is not just about achieving a certain cup size, but about achieving balance and harmony with the rest of your body.
Unlike bras, which use letters to indicate size, breast implants are measured in cubic centimetres (cc). Implant sizes typically range from 100cc to 800cc, though most commonly used sizes fall between 250cc and 450cc. The cc measurement refers to the volume of the implant, not the final bra size a patient will wear.
A common misconception is that a certain number of cc will always equate to a specific cup size. While it’s often stated that 150cc to 200cc equals about one cup size increase, this is a very general estimate. The actual increase in cup size will depend on several factors including the patient’s starting breast volume, chest wall width, and the dimensions of the implant itself.
In addition to volume, implants come in different shapes and profiles. Two implants with the same volume can produce different results depending on whether they have a low, moderate, or high profile. Profile refers to how far the implant projects from the chest wall. For example, a high-profile 300cc implant will create more projection than a low-profile 300cc implant, even though the volume is the same.
This is why choosing an implant based on cc alone is not advisable. What looks natural and proportionate on one person may appear too small or too large on another. The key to a successful outcome is a personalised assessment that takes into account your anatomy and your aesthetic goals.

Miss Anca Breahna takes a detailed and holistic approach when helping her patients select the right implant size. Her consultations are thorough and tailored to each individual, considering a variety of factors that influence the final result.
Every patient starts with a different anatomical foundation. Factors such as chest width, breast base diameter, skin quality, and nipple position all play a role in determining what implant size and shape will achieve the most balanced result. For example, a patient with a narrow chest will need a different implant profile than someone with a broader frame. Trying to place a wide, high-volume implant into a small frame can lead to complications such as implant visibility or unnatural results.
Another important consideration is how the implant will fit into your lifestyle. Patients who are highly active or involved in physical fitness may prefer smaller or more moderate implants to avoid interference with movement or long-term postural changes. Larger implants may be more likely to affect physical activity, cause discomfort during exercise, or require more support over time. Miss Breahna carefully discusses these lifestyle considerations to ensure the chosen implant aligns with your daily life.
Some patients want a subtle enhancement that improves symmetry and restores lost volume, especially after pregnancy or weight loss. Others are looking for a fuller, more dramatic transformation. Both goals are valid, but the path to achieving them will differ. Miss Anca Breahna ensures that the chosen implant reflects the patient’s vision while also remaining realistic, safe, and in harmony with their body proportions.
During consultations at Nuffield Health The Grosvenor Hospital in Chester or ASET Hospital in Liverpool, Miss Breahna conducts a full assessment including measurements and physical examination. She uses implant sizers and visual aids to help patients understand what different volumes and profiles would look like. Rather than simply picking a number, patients are guided through an educational and collaborative process. The goal is not just to choose an implant, but to choose one that will look and feel right long-term.
Selecting a breast implant is not a one-size-fits-all decision. The process involves both scientific measurement and personal preference, and it requires professional guidance. With Miss Breahna, patients are walked through every step in a structured and supportive way.
One of the most helpful parts of the implant selection process is the use of sizing bras and trial implants. Patients can try on different sizes under clothing to get a real-world sense of what various volumes might look like. While these methods don’t provide an exact match for the final result, they offer valuable insight into proportion and aesthetic.
Miss Breahna customises each surgical plan based on the patient’s body. This may involve choosing different implant shapes, combining a breast lift with augmentation, or addressing asymmetry. The plan is based on both physical measurements and patient input. The result is a surgical plan that is fully personalised.
Larger implants may sound appealing, but they are not always suitable for every patient. Overly large implants can cause complications such as skin stretching, discomfort, or premature sagging. Miss Anca Breahna prioritises safety and long-term results, guiding patients toward choices that will remain aesthetically pleasing and physically comfortable over time.
Patients often want to know what bra size they will be after surgery. It is natural to be curious, but predicting exact post-operative bra size is not always straightforward. Bra sizing is inconsistent across manufacturers and doesn’t always reflect the shape, projection, or contour of the breast after surgery.
Some patients will find they move up one or two cup sizes, while others may experience more dramatic changes depending on their starting point and chosen implant. For example, a 275cc implant might take a patient from an A cup to a full C cup, but this can vary. For more insight into C cup breasts and their popularity, see How Big Is a C Cup Breast and Why Is It So Popular? Bra fit also depends on the brand and style of the bra, which is why it’s best to focus on how the results look and feel rather than aiming for a specific size.
After healing is complete, typically 6 to 8 weeks after surgery, patients are encouraged to get a professional bra fitting. This ensures proper support and comfort while accommodating the new breast shape. Many women are surprised to find that their new implants require different styles or fits than they previously wore.
Breast implants don’t just increase volume. They also change the shape, contour, and upper fullness of the breast. A patient may wear the same cup size post-surgery but notice a dramatically improved silhouette. Shape, cleavage, and proportion often matter more than the number on a bra label.
Yes, especially right after surgery when your breast shape is still settling. However, once healed, many women find their new proportions actually make bra shopping easier, especially when fitted professionally.
Not exactly. Since sizing varies between brands, aiming for a specific cup size is unreliable. Your surgeon will focus on volume, proportion, and projection to get the desired look.
Yes. Implants can make underwires feel more prominent or less necessary depending on your shape and support needs. Many patients transition to non-wired or custom-fitted bras for comfort.
To some extent, yes. Implants are typically firmer and don’t compress the same way natural breast tissue does, especially in push-up bras.
Possibly. If the implant size is large relative to your existing breast, it can alter the perceived position of the nipples. In some cases, a breast lift is recommended for best symmetry.
Absolutely. A narrow chest or tight skin envelope means a large implant could cause complications. Safe sizing is always guided by your anatomy.
Yes. Most patients report increased awareness or discomfort when lying flat on their chest, especially with larger implants. Many adapt to side or back sleeping.
Unlikely. Most patients find their old bras no longer fit or support properly. Post-surgery bras are designed to support healing and new contours.
No. Cleavage depends not just on implant size, but on chest width, implant profile, and how close your breasts are naturally.
It can. Larger implants may subtly shift your centre of gravity or how you carry your shoulders. This is one of many factors considered during consultation.
