Underbust vs Overbust: How to Measure for the Perfect Bra Fit

How about we skip the "bra math" headache and get straight to the point?

“Affirmative”, you said....we know it!

We have all spent way too many hours tugging at a band that’s too tight or readjusting cups that just won't stay put. It turns out that most of us are wearing the wrong size simply because we were never taught the difference between two crucial numbers.

Finding your "soulmate bra" isn't about luck. It’s in the underbust and overbust meaning. These two bra size measurements are the foundation of a great fit, and once you know them, the guessing game is over.

Let’s get you measured so you can finally forget you’re even wearing a bra. wink...wink....

The Golden Rule: Preparation

Before you grab the measuring tape, and before we lead you on ‘how to measure bust and underbust’, there’s a rule & that’s pure GOLD.

Make sure you are wearing a non-padded bra or no bra at all. Padded cups add bulk that will throw off your numbers. You’ll also want a flexible measuring tape and a mirror to make sure everything stays level.

1. Measuring The Underbust (Your Band Size)

The underbust is the area directly beneath your breasts where the bra band sits. This is the most important measurement because the band provides about 80 percent of the support.

• Wrap the tape measure around your ribcage, right under your bust.

• Make sure the tape is snug and parallel to the ground.

• Exhale fully to get your smallest, most accurate ribcage measurement.

• The Math: If you get an even number, that is usually your band size. If you get an odd number, round up to the nearest even number. For example, a 31 inch measurement usually means you are a size 32.

2. Measuring The Overbust (Your Cup Size)

The overbust measurement is taken at the fullest part of your chest. This is the first step of cup size calculation and determines how much volume the cups need to hold.

• Wrap the tape around your back and across the fullest part of your breasts.

• The Key: Do not pull the tape tight here. It should be resting gently against your skin without compressing your breast tissue.

• Again, check the mirror to ensure the tape isn't sagging at the back.

Calculating Your Cup Size

Now that you have both numbers, for cup size calculation, you just need to find the difference between them. Each inch of difference represents one cup size.

Quick Tips for the Perfect Fit

Now that you are done with bra size measurement; its time for some quick tips! Numbers are a great starting point, but every brand cuts bras a little differently. Keep these "fit checks" in mind when you try things on:

• The Two-Finger Rule: You should be able to slide two fingers under the band comfortably. If you can fit more, it is too loose.

• The Gore Check: The center part of the bra (the gore) should lay flat against your chest bone. If it is hovering, the cups are likely too small.

• The Side View: Your breasts should sit midway between your shoulders and your elbows. If they are lower, you need more support from a firmer band.

At times, we think about how good it would have been if they taught things like ‘underbust and overbust meaning’ in biology lectures. Life thoda easy ho jata if we weren't out here trying to solve "The Case of the Missing Comfort" all by ourselves.

But don't worry. girlies, because we are doing it casually for you here at Underneat. No boring lectures, just the perfect bras fit to keep you feeling confident and chill.
