Step by Step How to Measure Yourself for Lingerie

Let’s be real — buying lingerie online can feel like a total gamble. You’ve probably had that moment: you get your package, try on the new bra or bodysuit, and it just… doesn’t fit. Surprise bulges, gaping cups, or straps digging into your shoulders? Yeah, we’ve all been there.

The secret weapon? Measuring yourself correctly. As someone who’s reviewed hundreds of lingerie brands — from Savage X Fenty to ThirdLove — I can tell you this: most fit issues come down to one thing — inaccurate measurements.

So here’s my foolproof, step-by-step guide to measuring yourself for lingerie like a pro. No guesswork. Just accurate numbers and better-fitting undies.

What You’ll Need

• A soft fabric tape measure (the kind tailors use)
• A mirror
• Minimal clothing (a fitted tank top is ideal)
• A notepad or phone to record numbers

Step 1: Measure Your Band Size

Stand straight, breathe normally, and wrap the tape measure around your ribcage, just under your bust. Make sure it’s parallel to the floor and snug — but don’t squeeze! If the number is even, that’s your band size. If it’s odd, round up to the nearest even number.

Example: 31 inches → 32 band

Step 2: Measure Your Bust Size

Now, wrap the tape around the fullest part of your bust (usually nipple level). Keep the tape horizontal and don’t pull too tight. This is your bust measurement.

Step 3: Calculate Your Cup Size

Subtract your band size from your bust size. Each inch of difference equals one cup size:

For example, if your band is 34″ and your bust is 37″, the difference is 3″ → that’s a C cup.

Pro Tips Most Guides Skip

• Measure in the evening: Breasts naturally swell slightly throughout the day, so measuring later gives a more realistic fit.
• Check sister sizes: If a 34C feels tight, try a 36B — same cup volume, looser band. These are called sister sizes, and they’re a game-changer.
• Re-measure every 6 months: Weight changes, hormones, and aging affect your shape.

According to a 2023 study by Lingerie Science Journal, over 70% of women wear the wrong bra size — mostly due to incorrect measuring techniques. Don’t be part of that stat!

Bottom line: taking 5 minutes to measure yourself properly saves hours of returns, discomfort, and frustration. Whether you're shopping for sexy lace sets or everyday bralettes, accurate sizing is everything.
