If you've ever ripped off a bra at the end of the day with a sigh of relief – you're not alone.
Most women are wearing the wrong bra size and don't even realize it. The result? Digging straps, slipping bands, uncomfortable cups, and a constant urge to go braless. But here’s the truth: the best bras for women don’t just support your body – it supports your confidence.
This guide will help you understand how bra sizes work, how to find your perfect fit, and what to look for when choosing a bra that truly fits you.
Why the Right Bra Size Matters
Wearing the wrong bra size can cause:
- Shoulder and back pain
- Poor posture
- Breast spillage or gaping
- Discomfort and self-consciousness
On the flip side, a bra that fits provides support, enhances natural shape, and boosts your confidence.
There’s no such thing as the "perfect" body, but we believe there is such a thing as a perfect bra.
The goal isn't to change how you look – it's to embrace what you have and feel amazing in your own skin, while giving yourself time to find the perfect fit.
Understanding Traditional Bra Sizes – And Why We Made It Simpler
Bra sizes are typically made up of two parts: a band size and a cup size.
-
Band size (the number): Measures the area around your ribcage, like 34 or 38.
-
Cup size (the letter): Refers to the volume of your breasts, like B, D, or DD.
📌 Quick Tip: A 34B and 36B aren’t the same—the cup size changes with the band. That’s why if you size up in the band, you usually size down in the cup to keep the same fit. This is known as sister sizing.
But let’s be honest—bra sizing can get complicated fast, especially for women who don’t fit into standard proportions. That’s where Nuderie does things differently.
How to Measure Your Bra Size at Home (with Cup Sizes)
It’s important to know how to measure your bra size, but we already mentioned that the “traditional” sizing isn't always applicable for everybody. (We’ll cover what we believe is a better fit for a more inclusive fit below.)
Step 1: Measure Your Band
- Wrap the tape snugly around your ribcage, directly under your bust.
- Round to the nearest whole number. If it’s even, that’s your band size. If odd, round up to the next even number.

Step 2: Measure Your Bust
- Measure around the fullest part of your bust, keeping the tape straight across your back.

Step 3: Calculate Your Cup Size (without a bra size chart)
- Subtract your band size from your bust measurement.
- The difference in inches = your cup size:
- 1 inch = A cup
- 2 inches = B cup
- 3 inches = C cup bra... and so on
Example: Band = 34, Bust = 37 → Difference = 3 → Cup size = C → Size = 34C
Our Simplified Sizing: S to 3XL
Instead of relying on tricky letter-number combos, Nuderie offers inclusive sizing from Small to 3XL. Why? Because real bodies aren’t formulas. Our sizing allows for:
-
More flexibility across different bust and waist proportions
-
Less guesswork when shopping
-
A more comfortable and forgiving fit
This system works especially well for women with non-traditional shapes—whether you have a smaller band with a fuller bust, or broader shoulders and a narrow frame.
If you're in between sizes, we recommend ordering a couple to find your perfect fit right away—no second guessing. Plus, with our easy return option, you can send back what doesn’t work and keep only what feels just right.
It’s a journey—but, with Nuderie, it’s a simple one. And we’re here to support you with styles that shape, uplift, and empower every step of the way.
How Should a Bra Fit? Your Fit Checklist
Band: Should sit straight across your back and feel snug on the loosest hook (you can tighten it over time).
Straps: Stay in place without digging. They should offer lift but not all the support.
Cups: No gaping, no spilling. Your breasts should sit comfortably inside the cup.
Center Panel: Should sit flat against your chest.
Underwire (if applicable): Should sit under your breast, not on it.
If anything feels off, it's likely the wrong size or style.
Choosing the Right Bra for Your Body Type
Petite: Look for light padding and plunge styles to enhance and lift.
Full-Busted: Go for wide straps, firm bands, and full-coverage cups.
Asymmetrical: Choose stretchy cup materials or removable pads.
Postpartum or fluctuating sizes: Consider wireless bras and adjustable options for flexibility.
There’s no one-size-fits-all here – just the size that fits you.
