Let’s be honest — finding your bra size can feel like trying to solve a puzzle in the dark. One minute you think you’re a 14C, then you try on another brand and suddenly you’re a 12DD. Sound familiar?
The good news? You don’t need a fancy fitting room or a lingerie expert to figure it out. With a tape measure, a mirror, and five minutes, you can measure your bra size right at home — no awkward fitting sessions required.
So, grab a cuppa, your measuring tape, and let’s find your perfect fit together.
Ever come home after a long day and can’t wait to take your bra off? Yep, that’s a sign.
Most women wear the wrong size without realising it. Here’s how to tell if your bra isn’t doing you any favours:
A customer once told us, “I thought bras were meant to be uncomfortable until I found my right size.”
Trust us — when it fits properly, you’ll never want to take it off.

This is where the magic starts. Your band provides most of the support — think of it as the foundation of your bra.
Here’s how to measure:
If it’s an even number, that’s your band size. If it’s odd, round up to the next even number.
So, if you measured 33 inches, your band size is likely 34. That’s 12 Aussie! Yep, you measure in inches then convert. Don’t stress our bra size conversion guide will help you otu.
It should feel firm, like a friendly hug — not a tight squeeze.
Quick story: A customer once told us she thought she was a 16 band her whole life. After measuring properly, she discovered she was actually a 14! Her new bras suddenly stopped riding up, and her shoulders thanked her.
Now for the fun bit — finding your cup size.
Here’s a cheat sheet:
You get the picture.
Example: If your bust is 38 inches and your band is 34, that’s a 4-inch difference — hello, 34D!
Don’t stress if your size changes from brand to brand. A Panache Sport 34D might feel firmer than a Freya Active 34D — that’s totally normal.

Q1: How often should I measure my bra size?
At least once a year. Your body changes — and so should your bra size. Weight loss, exercise, pregnancy, or even just time can make a difference.
Q2: Can I measure my bra size without a tape measure?
You can! Use a piece of ribbon or string, mark the spot, and measure it with a ruler. It’s old-school but it works in a pinch.
Q3: Why does my size change between brands?
Just like jeans, bras fit differently depending on cut and fabric. Don’t panic if you’re a 12E in one brand and a 14DD in another. The label isn’t what matters — comfort is.
Q4: What’s the most common measuring mistake?
Pulling the tape too tight. We get it — we all want that “snug” number. But if you can’t breathe, it’s too tight. Keep it firm, not squeezed.
Q5: What if I’m between two sizes?
Try both. Go smaller for more support, or larger for comfort. You might even find your “sister size” fits like a dream.
