Understanding your bra size starts with knowing what those numbers and letters actually represent. The right fit transforms how your clothes sit, how you move through your day, and how supported you feel from morning to night.
Here's what a 36G bra size means, plus we'll reveal the best bra styles for this bra size.
A 36G bra size consists of two measurements that work together to determine your fit. The number "36" represents your band size, or the measurement around your ribcage just below your bust. The letter "G" indicates your cup size, which reflects the difference between your bust measurement and your band measurement.
For a G cup, this difference is typically around 7 inches. Cup sizes are relative to band sizes. A 36G has the same cup volume as a 38F or a 34H. These are called sister sizes. Think of it this way: as the band gets larger, the cup letter gets smaller to maintain the same overall volume.
Many women are surprised to learn they wear a G cup. This size is more common than people think. Cup size alone doesn't determine breast size; it's the combination of band and cup that creates your unique fit.
Grab a soft measuring tape. If you don't have one, use a piece of string or ribbon and measure it against a ruler afterward. You'll also want a mirror to check that the tape sits level around your body. Wear a non-padded bra for the most accurate results.
Stand straight with your arms at your sides. Wrap the measuring tape around your ribcage directly under your bust, keeping it parallel to the floor. The tape should feel snug but not tight.
Measure around the fullest part of your bust. Keep the tape parallel to the floor and make sure it's not too tight or too loose. The tape should rest gently against your body without compressing breast tissue.

The band provides 80% of your bra's support, so it should sit horizontally across your back. If it rides up, it's likely too large. If the fit is only slightly off, try going down a band size and up a cup size to find your sister size, which would be a 34H. This maintains the same cup volume while giving you a snugger band.
When breast tissue spills over the top or sides of your cups, you need a larger cup size. This is one of the most common signs of an incorrect fit, especially with the fuller bust for a G cup. Consider trying a 36H or adjusting your band size if needed. Sometimes the issue isn't just cup size; the bra style might not suit your breast shape.
Gaps between your breast and the cup fabric, particularly at the top, could indicate several things. One possibility is the cup style might not suit your breast shape. For example, if you have more fullness at the bottom, a balconette might work better than a full cup. Start by learning your breast shape to see which bra styles are right for you.
Straps should stay in place without creating indentations in your shoulders. If they dig in, your band might be too loose, so try tightening it or even sizing down. If the straps still slip off, the straps might be too long, or you might benefit from a racerback style that keeps straps closer to your neck.
These provide strong support and coverage for everyday wear. Look for styles with wider straps and a higher center gore for better weight distribution. Full coverage bras work well under higher necklines and provide security during movement. For a comfortable and supportive fit, try the SoftForm Bra.

High-impact sports bras designed for larger cup sizes use compression and encapsulation to minimize movement during physical activity. Look for styles with adjustable straps, moisture-wicking fabric, and secure band construction. Honeylove's CrossFlex Activity Bra features the best elements of a supportive sports bra and wireless everyday bra combined into one.

Smooth, molded cups create a seamless look under fitted clothing. T-shirt bras are workhorses in any lingerie drawer as they disappear under clothes while providing reliable support. Look for styles with breathable fabric and comfortable band construction. The CloudEmbrace Bra is a modern take on the wireless t-shirt bra and features sturdy foam cups and smoothing wings.
