For many full-figured women, finding a comfortable, supportive bra can be a challenge. But what exactly is the “biggest” bra size, and where can you find bras that fit well in larger cup sizes? In this article, we’ll explore the world of plus-size bras and share our top 5 recommendations for comfortable, stylish options available on Amazon.

Understanding bra sizes: How big do they go?

Bra sizes aren’t standardized across brands, but generally, the largest commercially available bras go up to around a K or L cup (US sizing). However, some specialty brands offer even larger sizes, going up to O or P cups in some cases.

It’s important to note that cup size is relative to band size. For example, a 34H cup will be smaller in volume than a 38H cup, even though they’re both “H” cups.

How to measure yourself for the correct bra size

Before shopping for a bra, it’s crucial to know your correct size. Here’s a simple guide to measuring yourself at home:

  1. Measure your band size:
    • Wrap a soft measuring tape snugly around your ribcage, just under your breasts.
    • Round to the nearest whole number. If it’s even, add 4 inches; if it’s odd, add 5 inches.
    • This number is your band size.
  2. Measure your bust size:
    • Wrap the measuring tape loosely around the fullest part of your bust.
    • Round to the nearest whole number.
  3. Calculate your cup size:
    • Subtract your band size from your bust measurement.
    • Each inch of difference represents a cup size (1″=A, 2″=B, 3″=C, etc.).

Remember that these measurements are a starting point. Factors like breast shape, body type, and personal preference can affect your ideal fit. It’s always best to try on bras and adjust as needed for optimal comfort and support.
