Understanding 38G Breast size: Fit, Support, and Style for Full Figures

Women with 38G breasts often face a unique set of challenges when it comes to lingerie shopping, body support, and daily comfort. It can be difficult for women with this size to find well-fitting bras and comfortable lingerie, due to the variability in breast shapes, sizes, and inconsistencies in sizing systems. From finding the right bra size to choosing styles that flatter and feel good, having a full bust requires thoughtful solutions, not compromises.

At Olivia Paisley Intimates, we specialize in creating and curating lingerie for fuller-busted women. This guide breaks down what it means to have 38G breasts and how to navigate fit, fashion, and function with confidence.

What Does 38G Really Mean?

A 38G bra size refers to:

A band measurement of approximately 38 inches (around the ribcage)
A bust measurement (also called bust size) of about 47 inches (the fullest part of the chest), which is essential for determining proper bra fit

That’s a 9-inch difference, which places G cups among the fuller end of the size spectrum. In some sizing systems, such as those used in European countries, measurements are taken in centimeters rather than inches. Contrary to common misconceptions, G is not the same as a DDD in all sizing systems. G cup in UK sizing, for example, is different from G in US sizing. At Olivia Paisley, we use accurate international conversion to ensure the right fit for every woman.

Calculating Your Bra Size

Finding your correct bra size is the foundation for achieving the perfect fit and all-day comfort. To calculate your bra size, start by measuring your band size: wrap a soft measuring tape snugly around your ribcage, just under your bust, making sure it’s level and not too tight. Note this measurement in inches, this is your band size. Next, measure around the fullest part of your bust, keeping the tape comfortably taut but not pressing into your skin. Subtract your band measurement from your bust measurement; the difference determines your cup size. For example, if your band measures 38 inches and your bust measures 47 inches, you have a 9-inch difference, which typically corresponds to a G cup in UK sizes.

It’s important to remember that bra sizes can vary between brands and countries. UK sizes, European sizes, and even US sizes may use different systems, so always check the sizing chart for the specific brand and country you’re shopping in. Many brands provide a bra size chart on their website to help you calculate your size and find your perfect fit. If you’re unsure, don’t hesitate to get professionally measured or use an online bra size calculator. Taking the time to get the right measurements ensures you’ll find a bra that fits, flatters, and supports your body beautifully.

EU Bra Size Conversion for 38G

Navigating bra sizing across different countries can be complicated, especially when shopping for bras in European countries. If you wear a 38G in UK sizes, your equivalent in European sizes is typically an 85G. However, sizing can vary between brands, so it’s always wise to double check before making a purchase. Well known brands like Curvy Kate, Fantasie, Freya, Gossard, and Anita may each have their own sizing charts, so be sure to consult the chart on the brand’s website for the most accurate fit.

Using a bra size conversion chart is a helpful way to ensure you’re selecting the right size when shopping internationally. If you’re ever in doubt, reach out to a professional fitter or use the chat feature on a lingerie website for guidance. Taking these extra steps will help you find the perfect fit, no matter where you shop or which brand you choose.

Common Challenges for 38G Breasts

Women with 38G breasts may encounter:

Limited availability in mainstream retail stores
Discomfort from poorly fitting bras (digging straps, underwire pain, band ride-up)
Back, shoulder, or neck strain from inadequate support
Difficulties with sports bras or swimwear that provide both security and shape
Sizing and fit can differ significantly between brands, making it harder to find a consistent fit

But with the right lingerie, these challenges can be fully addressed.

Key Features to Look for in Bras for 38G Breasts

When shopping for bras in this size, construction matters more than ever, these features are essential for finding the perfect bra for 38G breasts. Look for:

✅ Full Cup Coverage

Prevents spillage, maintains a natural shape, and distributes weight evenly.

✅ Wide, Padded Straps

Alleviates shoulder pressure and improves overall comfort.

✅ Reinforced Underwire

Properly graded underwires lift without poking or collapsing.

✅ Strong, Supportive Band

Most bra support comes from the band, not the straps. A snug 38 band provides structure.

✅ Side Smoothing Panels

Offer a clean silhouette and help center the bust comfortably.

Tips for Wearing and Styling with 38G Breasts

Get professionally fitted at least once a year, body changes and so should your bras.
Rotate your bras: Having at least 3–5 good bras extends the life of each one.
Invest in specialty lingerie for sports, sleep, and swim. Each category serves a different need.
Embrace structure in your clothing: Dresses with built in support or V-necklines often flatter fuller busts.
When shopping online, use the filter function to quickly narrow down bras by your size, preferred style, or color for a more efficient search.
Note: Some brands use alpha sizing (such as XS) instead of traditional band and cup sizes. Always check the size conversion chart to ensure you select the correct fit.
Confidence is key: The right fit transforms not only how you look—but how you feel.

Bra Care and Maintenance

Caring for your bras properly is essential to maintain their perfect fit, support, and comfort. To keep your bras in top condition, always wash them by hand in cold water using a gentle detergent. Avoid using fabric softener or bleach, as these can break down the elastic and damage the underwire or straps. Never wring or twist your bras, gently press out excess water with a towel instead.

When drying, lay your bras flat in a cool, dry place away from direct sunlight to prevent fading and stretching. Store your bras with the cups facing up and not folded, to help them retain their shape and support. By following these simple care tips, you’ll extend the life of your bras and ensure they continue to provide the comfort and lift you need every day.
