How to Measure Lingerie Size at Home: Your Complete Guide to a Perfect Fit

You've found the perfect lace set. The style is exactly what you wanted. You add it to the cart — then pause.

What size am I?

It's a question almost every woman asks when shopping for lingerie online. And getting it wrong is frustrating: a bra that digs in, a bodysuit that pulls, a corset that doesn't close the way you imagined. The good news? Measuring yourself at home takes less than five minutes and makes all the difference between lingerie that feels like a second skin and one that ends up at the back of your drawer.

Here's exactly how to do it.

What You'll Need

Before you start, grab two things:

• A soft fabric measuring tape (the kind used for sewing — not a metal ruler)

• A mirror, or a friend who can help

That's genuinely all you need. No specialist tools, no guesswork.

Step 1: Measure Your Bust

Your bust measurement is the fullest part of your chest — across your nipples. Stand upright, breathe normally, and wrap the tape measure around the fullest point of your bust. Keep the tape parallel to the floor and snug but not tight — you should be able to slide a finger underneath comfortably.

Write down this number in centimetres.

For example: 92 cm bust.

Step 2: Measure Your Underbust (Band Size)

Your underbust is the measurement directly below your bust, where your bra band sits. Wrap the tape around your ribcage, just under your breasts. Again, keep it parallel to the floor — not angled up or down.

This measurement determines your bra band size (the number part of your bra size, like 10, 12, 14).

Write down this number too.

Step 3: Measure Your Waist

Your natural waist is the narrowest part of your torso — typically about 2–3 cm above your belly button, not at your hip bones. Breathe out naturally before measuring; don't suck in or push out.

This measurement matters especially for corsets, bustiers, bodysuits, and lingerie sets that are fitted at the waist.

Write this down.

Step 4: Measure Your Hips

Stand with your feet together and measure around the fullest part of your hips and bottom — usually about 20 cm below your natural waist. This is your hip measurement.

Hip measurements are especially important for G-strings, briefs, crotchless sets, and anything fitted through the lower body.

Write this down.

How to Calculate Your Bra Size from Your Measurements

Once you have your bust and underbust measurements, calculating your bra size is straightforward.

Band size corresponds to your underbust measurement, rounded to the nearest even number, then converted to Australian sizing. For reference:

• Underbust 63–67 cm → Band size 10

• Underbust 68–72 cm → Band size 12

• Underbust 73–77 cm → Band size 14

• Underbust 78–82 cm → Band size 16

Cup size is determined by the difference between your bust measurement and your underbust measurement:

• Difference of 12–14 cm → A cup

• Difference of 15–17 cm → B cup

• Difference of 18–20 cm → C cup

• Difference of 21–23 cm → D cup

• Difference of 24–26 cm → DD/E cup

So if your bust is 92 cm and your underbust is 77 cm, the difference is 15 cm — a B cup — and your band is a 14. Your bra size would be 14B.

Reading the Lingerie Seduction Size Chart

At Lingerie Seduction, all sizing is listed in Australian sizing, and most pieces are sized as XS/S, S/M, M/L, and L/XL rather than traditional bra sizing. Here's how your measurements map across:

Note: Always refer to the individual product size chart on each listing, as some styles may vary slightly in fit.

For example, if your bust measures 92 cm, your waist is 75 cm, and your hips are 101 cm, you'd typically wear a size 12 or M/L.

Tips for Getting the Most Accurate Measurement

Measure in your underwear, not over clothing. Even a thin layer of fabric can add centimetres to your measurements and push you into the wrong size.

Stand naturally. Don't slouch or pull yourself up extra tall — just your normal, relaxed posture.

Measure more than once. Take each measurement two or three times and use the average. It sounds fussy, but it's worth it.

Take your measurements at the right time of day. Your body can fluctuate slightly throughout the day, so measure in the morning for the most consistent result.

If you're between sizes, size up. Lingerie is meant to be comfortable as well as beautiful. A slightly larger piece can always be adjusted with straps or layering; one that's too small simply won't sit right.

Measuring for Specific Lingerie Styles

Different styles need slightly different attention to measurement.

Bra sets and lingerie sets: Both bust/cup and underbust measurements matter here. Our pieces are primarily designed for B to D cup ranges, so if you're outside this range, reach out to our team — we're happy to help you find styles that work beautifully for your shape.

Bodysuits and teddies: Focus on bust, waist, and hip measurements together, and check the total body length if it's listed — especially if you're on the taller or shorter side.

Corsets and bustiers: Your waist measurement is the star here. Most corsets are designed to cinch in by a few centimetres, so measure your natural waist accurately and look for a corset sized within 5–8 cm of that number.

Babydolls and chemises: These are the most forgiving styles. Bust measurement tends to be the most important guide, and the flowing silhouette accommodates a range of hip and waist sizes comfortably.

Plus-size lingerie: Our plus-size collection is designed with the same attention to fit and flattery as the rest of our range. Use the same measurement process above and refer to the specific size chart on each plus-size listing.

What to Do If You're Between Sizes

Lingerie sizing isn't one-size-fits-all — and that's okay. If your measurements land right in the middle of two sizes, consider the style you're shopping for:

• For stretch fabrics (mesh, lace, elasticated sets): size down, as these are designed to stretch and mould to your shape.

• For structured pieces (corsets, underwired bras): size up for comfort, especially around the band.

• For anything with adjustable straps: your exact cup or bust measurement matters less — straps can compensate for a half-size difference.

Why Getting Your Size Right Matters

The right-fitting lingerie isn't just about aesthetics — it's about how you feel wearing it. When lingerie fits properly, it moves with you, sits smoothly against your skin, and gives you that effortless confidence that can't be faked.

A piece that's too tight creates discomfort and visible lines. Too loose, and it loses the structure and shape that make it beautiful in the first place. Taking five minutes to measure yourself before you shop is the single best thing you can do to ensure your order feels as good as it looks when it arrives.
