Understanding the 46A Bra Size

The 46A Bra: Style for a Unique Size Profile. In the world of lingerie, many assume that larger band sizes always pair with fuller cups. The 46A bra defies that assumption. This size combines a wide band (46 inches around the ribcage) with an A cup (approximately a 1-inch difference between bust and band measurements). Though rare in retail offerings, it reflects the very real needs of individuals who have a broader frame or plus-size torso with a smaller bust.

Whether due to natural body shape, surgical changes, or weight distribution, the 46A size serves a valuable role in inclusive sizing. Let’s break down what makes this size unique and how to find bras that actually work for it.

What Does 46A Really Mean?

In bra sizing:

• 46 refers to the band size — the measurement around your ribcage, just beneath your bust. It typically fits those with a ribcage measurement around 41–43 inches, depending on the brand.

• A indicates a cup volume that is 1 inch larger than the band measurement at the fullest part of the bust.

So a 46A means you have a wider underbust but relatively shallow breast projection. This is a low-volume cup on a full band, and it presents a unique fit challenge—especially in mainstream bra ranges that often exclude this combination.

Common Fit Challenges in 46A

The main difficulty in this size is that most brands don’t manufacture small cups in extended bands. As a result, people often end up wearing:

• Too-large cups (e.g., 46C or 46D) that gape or wrinkle

• Too-small bands (e.g., 42A or 44A) that pinch or ride up

• Bralettes or sports bras with insufficient support

These compromises can lead to discomfort, improper posture, and low confidence. The key to comfort in a 46A bra is firm, wide-band support with shallow, well-contoured cups.

What to Look for in a 46A Bra

Here’s what defines a good bra for a 46A size:

✅ Wide, Supportive Band

Look for bands that lie flat across the back, with at least 3-4 hooks for even distribution. The band should be snug but not restrictive.

✅ Shallow Cups

Molded or lightly lined cups that accommodate a low bust projection will give a natural shape without gaping.

✅ Side Panels & Full Coverage

Extra fabric on the sides helps contain and smooth the underarm area—important in wider band sizes.

✅ Adjustable Straps

Wider straps offer better weight distribution and should be adjustable to avoid digging in.

✅ Wireless or Soft-Cup Options

Since bust support is less of a concern with an A cup, wireless bras can offer excellent comfort while still giving structure.

Brands That May Offer or Customize 46A Bras

Although availability is limited, several brands offer extended bands and may carry 46A or sister sizes close to it:

• Leading Lady – Known for comfort bras in extended sizing

• Glamorise – Offers wide bands and wire-free support for full figures

• Decent Exposures – Custom-sized bras made-to-order, including rare sizes
