34G Bra
A Comprehensive Guide to 34G Bras: Styles, Sizing, and Commonly Asked Questions


Finding the perfect bra that fits well and provides ample support can be a daunting task, especially for women with larger busts. One size that often falls within this category is the 34G bra. In this comprehensive guide, we'll delve into the world of 34G bras, explore bra cup sizes, international equivalents, sister sizes, and discuss various bra styles available in 34G. We'll also address commonly asked questions to help you find the best-fitting and most comfortable bra for your unique needs.

Understanding Bra Cup Sizes:

Bra cup sizes play a significant role in determining the fit and support a bra offers. The cup sizes are indicated by letters (A, B, C, D, etc.), with each letter representing an incremental increase in breast volume. For instance, a 34G bra would have a larger cup size compared to a 34D bra.

The letter G in the 34G bra size indicates a relatively larger cup volume. However, it's essential to understand that cup sizes are relative to the band size. As the band size increases or decreases, the cup size also changes to maintain the same volume. Therefore, the cups of a 34G bra will hold the same volume as the cups of a 36F bra or a 32H bra.

International Equivalent Cup Sizes:

It's important to note that the cup sizing system can vary slightly across different countries, which can lead to confusion for those seeking a specific cup size. For instance:

  • In the UK and Europe, the cup sizes progress as DD (E), E, F, FF, G, GG, H, HH, and so on, after D.
  • In the US, the cup sizes progress as DD (E), DDD (F), G, H, I, J, K, and so forth, after D.
  • In Australia and New Zealand, the sizing is similar to the UK system.

As a result, a 34G bra in the UK would be equivalent to a 34F bra in the US or Australia. Therefore, understanding international cup size equivalents is crucial, especially when shopping for bras from international retailers or brands.

Sister Sizes:

Sister sizes are bras with different band sizes but the same cup volume. This means that if a 34G bra feels too tight in the band, you can try going up a band size and down a cup size to maintain the same cup volume. In this case, the sister sizes of a 34G bra are 36F and 32H.

For example, if a 34G bra feels a bit snug around the ribcage, you could try a 36F instead, which will have a slightly larger band but an equivalent cup volume. Keep in mind that the fit may still vary slightly due to the band adjustment.

Measurement Guide for 34G Bra Size:

Knowing how to measure your bra size accurately is crucial to finding a comfortable and supportive fit. To find your correct 34G bra size, follow these steps:

  1. Measure Your Band Size: Take a measuring tape and measure snugly around your ribcage just below your bust. Make sure the measuring tape is parallel to the ground and not too tight. Round this measurement to the nearest even number to determine your band size. If the measurement is an odd number, add one inch to get an even number. For example, if the measurement is 33 inches, round it up to 34 inches.
  2. Measure Your Bust Size: Stand straight with your arms at your sides and measure around the fullest part of your breasts, ensuring the measuring tape is parallel to the ground.
  3. Calculate Cup Size: Subtract the band measurement from the bust measurement. The difference in inches will correspond to the cup size based on the following chart:
    Difference (in inches) Cup Size
    1 A
    2 B
    3 C
    4 D
    5 DD (E)
    6 F
    7 FF
    8 G

For example, if your band measurement is 34 inches and your bust measurement is 42 inches, the difference is 8 inches, indicating a 34G cup size.

Bra Styles in 34G:

Now that we've covered the sizing and measuring techniques, let's explore the different bra styles available in 34G:

  1. T-shirt Bras (or Contour Bras): T-shirt bras are designed with smooth, molded cups that create a seamless look under fitted clothing. They offer excellent coverage and shaping while providing a natural, rounded appearance. T-shirt bras in 34G are a must-have for everyday wear, ensuring a sleek silhouette with a comfortable fit.
  2. Balconette Bras: Balconette bras have a lower cut along the top of the cups, creating a more open neckline. They provide lift and support, enhancing the natural shape of the breasts. Balconette bras are perfect for tops or dresses with lower necklines and can be a flattering option for 34G cup sizes.
  3. Full Cup Bras: Full cup bras provide maximum coverage and support, making them ideal for larger breasts. They offer a secure fit, prevent spillage, and distribute weight evenly, ensuring all-day comfort. Full cup bras in 34G are suitable for various activities and are especially beneficial for those seeking extra support.
  4. Plunge Bras: Plunge bras have a deep, V-shaped neckline that plunges between the breasts, making them a fantastic choice for low-cut tops and dresses. Despite the revealing neckline, plunge bras in 34G provide excellent support and lift, creating a flattering and alluring look.
  5. Sports Bras: For women with larger busts, investing in a high-quality sports bra is crucial for comfortable and supported workouts. Sports bras designed for 34G cup sizes offer maximum support, minimize bounce during high-impact activities, and reduce strain on the shoulders and back.
  6. Lace Bras: Lace bras are elegant and feminine, making them a popular choice for special occasions or when you want to add a touch of luxury to your lingerie collection. Look for lace bras that have supportive features and are designed to provide comfort and shaping while showcasing beautiful lace detailing.
