How big is a C cup？

How do I know I wear a C-cup?

When choosing the perfect bra, it’s essential to understand that your bra size consists of two parts: the band size (the number) and the cup size (the letter). For example, in a 34C bra, 34 represents the band size, and C represents the cup size.

To determine your cup size, you'll need to take two key measurements:

1. Ribcage measurement – taken right beneath your breasts.
2. Bust measurement – taken at the fullest part of your chest.

Does a C cup count as big?

According to HSIA's size chart, if the difference between these two measurements is around 5-6 inches, you would wear a C cup. The cup size shows how much your breasts project from your ribcage. However, bra sizing may vary slightly between different brands. For instance, while you may wear a C cup in HSIA bras, you might find yourself needing a B or D cup in another brand’s size chart. That’s why it's essential to update your measurements regularly and use them when shopping for bras from any brand.As of October 18, 2024, it’s always a good practice to recheck your size before purchasing to ensure a comfortable and accurate fit.

What is the difference between 34C, 36C, or 38C?

If you’re wondering about the difference between 34C, 36C, and 38C, it's important to note that the cup size (C) reflects a 5-6 inch difference between the bust and ribcage measurements in all three sizes. However, the actual volume of breast tissue varies. A 38C bra will have a larger breast volume than a 36C or 34C because of the wider band size.

By October 18, 2024, it's recommended to explore sister sizes, such as 34D or 38B, if you're considering trying different band sizes while maintaining similar cup volume. These sizes accommodate different band sizes while keeping a similar fit.

What bras are the best for C cups?

C cups are one of the most common bra sizes, making it easier to find options compared to smaller sizes like A or larger sizes like F. However, not all bras are made equal, even in such a popular size. Choosing a bra that fits well, provides support, and feels comfortable is crucial, especially for women with C cup breasts. The key is to find bras that are true to size, well-constructed, and suitable for your everyday needs.

Here are some of the best bras for C cups that I recommend from HSIA:

With the classic design and a multitude of trendy colors, you will love HSIA's signature lace bras. They feature full coverage cups, underwires, adjustable straps, and fine fabric, just perfect for the C cups. You can see how other girls present them from our instagram@wearhsia.

HSIA seamless comfort bras

Who can resist such a smooth and comfortable look from bras like these? I say we all need one of these to bring us comfort in a long and tiring day. It is like your second skin, you forget it exists yet the feeling of softness is so real.

HSIA invisible cohesive bras

A great choice to pair with the backless or shoulderless dress. It is small and can easily become invisible under whatever you wear in its neutral colors. Don't worry, it is sticky, and it won't come off, especially with C cups. And it is made of skin-friendly silicone, which won't cause you discomfort. Just remember to wash it properly and air it to dry after use. This style doesn't need as many sizes as the others, its size chart runs as below, and you can choose your size based on your regular bra size.
