Why Knowing Your Bra Size Matters
Before jumping into measurements, let’s talk about why bra fit is so crucial:
Better Posture
Enhanced Bust Shape
Reduced Breast & Shoulder Pain
Clothes Fit More Flatteringly
Improved Confidence
Your perfect bra fit can completely change the way you feel and carry yourself—and measuring it right is the first step.
How to Measure Bra Size at Home: Step-by-Step
You’ll need:
A soft measuring tape
A non-padded bra or go braless
A mirror or someone to assist
1. Measure Your Band Size (Underbust)
Wrap the measuring tape around your ribcage, directly under your bust.
Make sure it’s snug and level all the way around.
Round to the nearest whole number.
If it’s even, add 4 inches. If it’s odd, add 5 inches.
Example: 31 inches = 36 band size
2. Measure Your Bust Size (Overbust)
Place the tape over the fullest part of your breasts.
Keep the tape comfortably snug but not tight.
Round to the nearest whole number.
3. Calculate Cup Size
Subtract the band size from the bust measurement.
Each inch equals a cup size:
Difference (Bust - Band) | Cup Size |
---|---|
1 inch | A |
2 inches | B |
3 inches | C |
4 inches | D |
5 inches | DD or E |
Example: Band = 36, Bust = 39 → 39-36 = 3 → Cup Size C
So, your bra size is 36C.
Common Mistakes Most Women Make While Measuring Bra Size
Even if you know the steps, many women still fall into these traps:
Wearing padded or push-up bras during measurement
Not measuring the band snugly enough
Ignoring weight gain or loss over time
Assuming bra size is the same across all brands
Forgetting to remeasure after pregnancy or hormonal changes
At Trendy Micho, we always advise: Re-measure your bra size every 6–12 months—especially if your body is changing.
Signs You’re Wearing the Wrong Bra Size
The band rides up your back
Your shoulders hurt from the straps
Cups are gaping or spilling
Underwire pokes or doesn’t sit flat
You constantly adjust your bra all day
If any of this sounds familiar, it's time to go back to basics and learn how to measure bra size correctly.
Pro Tips for the Perfect Bra Fit
Try bras on at the end of the day when you're most bloated
Test the fit on the loosest hook—it gives you room to tighten later
Bend forward when putting on your bra to settle your breasts into the cups
Scoop and lift your breast tissue from underarms into the cup
Small tweaks like these make a big difference in daily comfort and breast support.
