Understanding the 28G Bra: A Guide to Fit, Support & Style. When it comes to bra sizing, the number of options can be overwhelming—and for those wearing a 28G bra, it often feels like finding the right fit is a treasure hunt. But contrary to what many assume, a 28G does not mean a “huge” bust—it simply reflects a specific ratio of a small band with a full cup. And for women with petite frames and larger busts, this size is not only common, but essential to wear correctly for posture, comfort, and confidence.

At Olivia Paisley Intimates, we champion size inclusivity and believe that no woman should settle for a bra that doesn't fit just right. This blog breaks down everything you need to know about the 28G bra—from sizing myths to fit tips and the styles that actually work.

What Does 28G Actually Mean?

Bra sizes are made up of two components: the band size (the number) and the cup size (the letter).

28 refers to the ribcage measurement in inches, just below the bust.
G refers to the cup size, which is calculated based on the difference between the bust and underbust measurements.

So a 28G bra is designed for someone with a very small ribcage and significant bust projection—typically a 9-inch difference between band and bust measurements.

Important to Know:

A 28G is not equivalent to a 34G. As the band size increases, the cup volume also changes. A 28G has the same cup volume as a 30FF, 32F, or 34E—this is known as “sister sizing.”

Why 28G Is Often Hard to Find

Most mainstream retailers stock sizes starting at 32 or 34, meaning those with smaller frames and larger busts are often underserved. This lack of availability leads many women to wear the wrong band size—often sizing up in the band and down in the cup, resulting in poor support, discomfort, and posture issues.

The Impact of the Wrong Size:

Bands that ride up the back
Cups that dig in or gape
Straps carrying too much weight
Chronic neck and shoulder pain

Wearing the correct size, especially a snug 28 band with the appropriate cup volume, redistributes weight properly and lifts the bust from the band, not the straps.

Best Bra Styles for a 28G

1. Full-Cup Bras

Offers maximum coverage and structure. Ideal for everyday wear and long-lasting support.

2. Balconette Bras

Give a lifted, rounded shape with slightly less coverage—perfect for open necklines.

3. Plunge Bras

Engineered for deep V-necklines, many 28G plunge bras now include reinforced side support to maintain lift.

4. Sports Bras (High Impact)

Designed to minimize bounce without compressing the bust unnaturally. Look for encapsulation styles with adjustable bands.

5. Wireless Bras (Structured Soft Cups)

Modern wireless bras in technical fabrics can offer surprising support, provided they have reinforced bands and cup shaping.

Fit Tips for 28G Bras

Always fit the band first. It should feel snug on the loosest hook—firm but not painful.
Scoop and swoop. This fitting technique ensures breast tissue is fully encapsulated in the cups.
Avoid sister sizing unless necessary. You want the support of a true 28 band if that's your actual underbust measurement.
Look for UK/EU sizing consistency. UK brands like Panache, Freya, and Fantasie often carry 28G bras with excellent engineering.
