30C Breast Size
Although C cup breasts are generally considered above average in size, the cup size is not the only determinant of the relative size of a woman’s breasts. A common misconception is that cup sizes have the same size regardless of the band sizes. In fact, cup sizes actually get larger as the band size gets larger since they are sized in proportion to a woman’s band measurement. For example, a 30C bra cup is almost identical in size to the cup of a 28D, a 32B or a 34A bra. In this comparison, the 30C bra fits a woman who has a smaller bone structure than a woman who wears a 32B or a 34A. Continuing with this example, a woman who wears a 30C has a larger bone structure compared to the frame of women who wear a 28D. A 30C probably looks proportionally large on a woman who has a small bone structure, but in terms of volume and actual size, 30C breasts are not particularly large even though they fall into the category of a “C” cup.
Like all breast sizes, the appearance of 30C boobs can vary greatly depending on lifestyle factors, genetics, and the patterns in which a woman’s body stores fat. For exapmle, if a woman is a «pear shape» (defined as carrying most of her weight in her bottom half), 30C size boobs would look pretty small from the front since her hips are proportionally wider than her chest. If this same woman carried minimal body fat in her stomach, her 30C breasts would look much more noticeable from the side since her stomach is flat which would make her breasts appear to protrude visibly. If a woman is shaped like an «apple,” meaning that she carries her body fat primarily in her stomach, 30C boobs would appear to be relatively small since there would be little definition between her breasts and stomach. If a very slender and narrow hipped woman had 30C breasts, her breasts would look large in proportion to her slim frame, but they would still look very small if compared to a woman who, for example, had 36C breasts.
30C natural breasts tend to be relatively perky since they are not heavy enough to cause significant sagging. Although 30C breasts may look somewhat large on a woman who has a small frame, the overall breast size is not considered particularly large so some women with this size may be inspired to get breast implants. You will find further discussion about increasing a 30C bra size with breast implants in the next section. Statistically, natural 30C size breasts are relatively uncommon because most women who have a small enough frame to have a size 30 band size tend to have very little breast tissue naturally.
Even though 30C breasts are relatively large considering the small frame of a woman with a 30 band size, some women with this size consider getting implants to increase their bust size. In particular, if a woman is pear shaped, she may want to increase her chest size in order to balance out the volume of her lower half. Like hair stylists who recommend that clients should dye their hair within a few shades of their natural color, surgeons tend to recommend that a woman pursue implants that are only one or two cup sizes larger than her original size if she wants to achieve a natural look. According to a survey conducted in 2012, the most commonly requested increase in size was two cup sizes.* Considering the recommendations of plastic surgeons, women with natural 30C breasts would appear to have a relatively natural looking bust if they opted to have a breast augmentation that brought them up to a 30D or 30DD. A woman with a 30C bust, however, would be more likely to look obviously surgically enhanced if she were to request implants that would bring her up to a 30E bra size or larger. Although it can be tempting to have a significant increase in size, you should keep in mind that many women who pursue breast implants that are too large for their frame end up having breasts that look bolted on to their chests in an unnatural way.
If on the other hand, a 30C bra size is the desired size to reach after a breast augmentation from a smaller size, starting with a 30A or a 30B would create the most natural look. However, starting from a 30AA bra size would probably result in a very unnatural looking augmentation.
Like most breast sizes, the appearance of 30C breasts with clothes on depends on a woman’s body shape, the bra that she chooses to wear, and her clothing choices. Regardless of body type, wearing a push up bra with a tight top will make the breasts appear more noticeable than they would if a woman was wearing no bra and a baggy sweatshirt. Generally speaking, the thinner a woman is in her midsection, the larger her breasts will appear proportionally because fabric lays across the part of the body that protrudes furthest. Especially if a 30C sized woman wears a padded push-up bra, her breasts will definitely be noticeable.
A 30C bra will be noticeably larger than that of smaller cup sizes with the same band measurement. However, the difference between a 36D and a 36A is much more prominent than the visible difference between a 30A and a 30D bra size. Boobs that require a 30C cup size are most likely the size of a small handful; a 30B would be a small sized bump; and a 30A would appear to be nearly flat-chested.
