Introduction

“One of my ex-husbands thought I had a breast job. They looked bigger. I just got the proper lingerie.”

-Cybill Shepherd; American actress and singer

Nothing kills your vibe faster than an ill-fitting bra. When you've got straps sticking in, cups gasping, weeping, and the band riding up, it's an instant bus kill. The culprit here is wearing the wrong bra size. So many women wear bras that don't actually fit them. And it all comes down to not knowing what is a cup size or how to measure bra size correctly. 

In this blog, we are going to tell you that finding your perfect fit is not rocket science. It's all about referring to the right bra size calculator and following a few tips for choosing the right bra. After all, when it comes to bra sizes or women's lingerie, the idea is not just to think about support and looks, but also about confidence, comfort, and feeling fabulous in your own skin.

What Is a Bra Cup Size?

Your bra cup size is the measurement of how much breast tissue your bra needs to hold. It is ascertained by the difference between your band size and your bust size. 

Where the band is the foundation of your bra, the cup size is the room where your bust gets to sit in comfortably. 

Some bra cup sizes examples are A, B, C, D, and beyond. These numbers and letters help you find the perfect fit. 

For example;

If your band measures 34 inches and your bust is 36 inches, the difference is 2 inches. That equals a B cup. If the difference is 3 inches, it would be a C cup.

How To Measure Bra Size

If you've ever wondered how to measure bra size at home or tried random hacks, let us help you out. Measure around the fullest part of your bust. Subtract your band size from this bust measurement. The difference is going to determine your cup size. This is the simple math behind how to calculate bra size. And see, it's very simple and there's no stress or confusion.

1. Calculate Band Size

  • Wrap a soft measuring tape snugly under your bust, right where the band of your bra is going to sit. 
  • Just keep it level. It should not be too tight or too loose. 
  • If the number is odd, round it off to the nearest even number. 

For instance, if you measure 31 inches, your band size is 32. 

2. Calculate Cup Size

  • Measure around the fullest part of your bust. 
  • Subtract the band size from the bust measurement. 
  • The difference is going to determine your cup size. 

This is the simple math behind how to calculate bra size. See, it is very simple and there is no stress or confusion.

How To Know If A Bra Fits Perfectly?

Take a look at this checklist to know that your bra cup size is perfect. Once you know how to calculate bra size, rest assured that you are going to be able to get it right every single time. 

  • The band of your women's bra should sit snugly; it should not be loose, and it should not dig in. 
  • Your bra cups should fully enclose your bust without spillage. 
  • Straps are supposed to stay in place and should not leave marks. 
  • The middle part of your bra should lie flat against your chest. 
  • There should be no wrinkles, bulges, or awkward gaps. 
  • Different kinds of women's bras, such as a T-shirt bra for women, should be comfortable enough to wear all day without adjusting.
  • Sports bras for women are designed to hold your breasts in place comfortably without suffocating you, so ensure the bands don’t bite into your skin.

Key Tips For Choosing The Right Bra

Once you know how to measure your bra size, picking the right bra style is also important. Take a look at these tips for choosing the right bra;

  • Know Your Size - You can use the Savvyy Bra Size Calculator regularly to know your perfect bra size.
  • Consider Your Outfit - A t-shirt bra for women is going to literally vanish under fitted tees, whereas a plunge neck bra is perfect for low-cut dresses. Therefore, choose your bra wisely.
  • Check Support and Comfort level - For workouts, nothing can beat the comfort and support of a women's sports bra.
  • Pay Attention to Comfort - Lace is sexy, and cotton is breathable. Take your pick accordingly.
  • Replace Worn Bras - Bras have a shelf life. Therefore, it is important not to cling to old ones and replace them when required.
