Your Complete Cup Bra Size Chart in Malaysia: How to Measure for Comfort

Are you experiencing the same? Finding the right bra size can feel harder than finding the perfect jeans. Too tight, too loose, cups that gape, straps that dig… we’ve all been there. And the truth is, many women in Malaysia are still wearing the wrong bra size without realising it. (Yikes!)

That’s why understanding your measurements and using a cup bra size chart properly can be a total game-changer. 

Whether you’re shopping online, replacing old bras, or looking for everyday comfort, this guide will walk you through exactly how to measure yourself and find a bra that truly fits.

No complicated terms. No confusing charts. Just real, practical help, the Celessa way.

Why Getting Your Bra Size Right Matters

A well-fitted bra does more than just look good under clothes. It:

• Supports your bust properly

• Improves posture

• Reduces back, shoulder, and neck strain

• Makes you feel more confident and comfortable all day

For women, achieving these benefits starts with a complete understanding of your bra size and fit by consulting a cup bra size chart, taking accurate measurements, and knowing your individual body shape are all essential to ensure comfort and support.

If your bra feels uncomfortable by lunchtime, chances are it’s not you; it’s the size.

Understanding Bra Sizes in Malaysia (Band + Cup)

Before we jump into the cup bra size chart, let’s break down how bra sizing actually works. Bra cup size refers to the volume of the breasts, not just the letter, and is determined by the difference between your bust and band measurements.

A bra size has two parts:

1. Band size: the number (e.g. 70, 75, 80)

2. Cup size: the letter (A, B, C, D, etc.)

To measure bra size accurately, you need to measure both your band size and bust size. A bra size calculator can help you measure bra size and determine your correct fit by inputting these measurements, often allowing you to choose between inches or centimetres.

It's also important to note that UK sizing often uses double letters (DD, FF, GG) for bra cup size, while US sizing typically uses single letters (D, DDD/F, G).

Band Size (The Number)

This refers to the measurement around your ribcage, just under your bust.

In Malaysia, band sizes usually follow EU sizing:

• 70 (around 68–72 cm)

• 75 (around 73–77 cm)

• 80 (around 78–82 cm)

• 85 and above

Some brands may list band sizes in inches as well as centimetres. Inch-based sizing refers to the circumference of the band around your body.

When measuring, make sure you are keeping the tape measure comfortably snug (not too tight) and positioned directly under your bust, keeping the tape parallel to the floor for accuracy.

To read a bra size chart, measure your ribcage and the fullest part of your bust, then subtract the band measurement from the bust measurement to determine your cup size.

Cup Size (The Letter)

Cup size is based on the difference between your bust measurement and your underbust measurement, and not how “big” or “small” you think your chest is.

The smallest cup size is typically an A cup, which represents the smallest standard breast volume. Cup sizes indicate breast volume, and the difference between your bust and band measurement determines your cup size.

This is where many people get confused (and why a cup bra size chart is so important).

How to Measure Your Bra Size at Home (Step-by-Step)

• Wear a non-padded bra or no bra

• Take your underbust measurements by wrapping the measuring tape snugly around your ribcage, just under your bust

• Ensure the tape is in the correct position (straight and level around your body) and keep the tape comfortably loose, not too tight or too slack

👉 This number helps determine your band size

Step 2: Measure Your Bust

• Measure your bust size by wrapping the tape around the fullest part of your breasts

• Keep the tape relaxed and properly positioned around the part of the bust that is fullest, ensuring you are keeping the tape comfortably snug but not tight for an accurate measurement

• Stand straight and breathe normally

👉 This number is used to calculate your cup size

Body Measurements Beyond the Bust: Waist, Hip, and More

When it comes to finding your perfect bra size, it’s easy to focus only on your bust and underbust. But for a truly comfortable fit, it’s worth taking a closer look at your full set of body measurements, and that includes your waist and hips.

Why do these extra measurements matter?

Your waist and hip measurements can influence how a bra’s band sits on your body, especially if you prefer wider bands or styles that offer more coverage. A band that fits well around your torso (not just under your bust) helps ensure your bra stays in place and provides the support you need all day.

Cup Bra Size Chart Malaysia (Simple Version)

On this page, the chart below lists band sizes across the top and cup sizes down the side. As you move down the column, cup volume increases, helping you find the most accurate fit.

Here’s a general cup bra size chart commonly used in Malaysia and nearby regions:

For example: If your underbust is 75 cm and your bust is 89 cm: 89 – 75 = 14 cm → B Cup 

Your bra size would be 75B.

Common Bra Sizing Mistakes (You’re Not Alone)

If you’ve ever felt like bras are just uncomfortable in general, one of these might sound familiar:

Before you make a purchase, remember that choosing the wrong cup bra size can lead to discomfort and, in many cases, bras cannot be exchanged or returned if purchased incorrectly. Always double-check your measurements before completing your purchase.

Note: If you are in between sizes, it is advisable to go for a bigger cup size.

Tip: If the band is too tight, go up one band size and down one cup size; if it is too loose, go down one band size and up one cup size.

❌ Wearing the Wrong Band Size

A band that’s too loose won’t support you properly. A band that’s too tight causes discomfort and red marks.

❌ Assuming Cup Size Is the Same Across All Brands

Cup sizes can feel different depending on bra design, fabric, and cut. That’s why trying different styles matters.

❌ Not Re-Measuring Over Time

Weight changes, pregnancy, hormones, and ageing can all affect your size. Re-measure every 6–12 months.

How to Know If Your Bra Fits Properly

Once you’ve found your size using the cup bra size chart, check the fit:

✔ The band sits straight across your back
✔ Cups fully contain your bust (no spilling or gaping)
✔ Straps stay in place without digging
✔ The centre gore lies flat against your chest
✔ You feel supported but comfortable

If your bra ticks all these boxes, congrats, you’ve found the one.

Choosing the Right Bra Style for Your Size

Size is important, but style matters too.

• Small to medium cups (A–C): Lightly padded, balconette, or wireless bras for natural shaping

• Medium to fuller cups (C–E+): Full-coverage bras with strong support and wider straps

• Everyday wear: Soft, breathable materials for all-day comfort

• Special occasions: Seamless or smoothing bras for a clean silhouette

Bra and undergarment sizes are available in a wide range, including XS, XL (also known as EL), and XXL, to ensure the right fit for every body type.

Just like with bras, finding your correct panty size or shapewear size requires accurate waist and hip measurements. 

For best results, measure your waist at the natural indentation of your waistline (this is usually the narrowest part of your torso). Use a soft tape measure and keep it comfortably loose around your waistline and hips to determine your ideal panty or shapewear size.

Visiting a store for a professional fitting can help you find the perfect size for bras, panties, and shapewear, ensuring comfort and support for everyday wear.

At Celessa, bras are designed with real bodies in mind by combining accurate sizing with comfort-focused cuts.
