Read moreWhat Is The Smallest Bra Size?

When it comes to finding the perfect bra, many women with smaller busts face a unique set of challenges. Ever wondered, “What is the smallest bra size?” you are not alone. Finding the right fit for smaller busts can be quite an adventure, but don’t worry; we’re here to navigate through it together. This guide will help you understand the nuances of bra sizing, explore options for petite sizes, and introduce you to ThirdLove’s approach to bras for small breasts.
Understanding Bra Sizing
First things first, bra sizing can seem like a puzzle, but once you get the hang of it, it’s pretty straightforward. Bra size consists of the band size (the number) and the cup size (the letter). The band size is the measurement around your ribcage directly under your breasts, and the cup size refers to the difference between your bust measurement (around the fullest part of your breasts) and your band size.
For example, if your band size is 32 inches and your bust measurement is 34 inches, the difference is 2 inches, which translates to a cup size of A. In this case, your bra size would be 32A.
Smallest Standard Bra Sizes
When it comes to the smallest bra cup size, AA is generally considered the smallest in standard sizing. However, you can get AAA with some specialty brands. Band sizes traditionally start from 30 or 32, although some specialty brands go as low as 28. Bra sizes are relative, so sometimes a 30A and a 32AA might feel similar because when the band size increases, the cup volume changes even with the same letter.
ThirdLove’s Approach to Small Sizes
At ThirdLove, we believe small-busted women want the same level of attention to detail in both comfort and style as everybody else. That is why we offer a wide range of sizes, including bands starting at 30 and cups as small as AA. Our half-cup sizes also cater to women who fall between standard measurements, ensuring a fit that’s tailored to you.
