How to Measure Your Bra Size According to the Experts and Affordable Luxury Brands to Shop

How to Measure Your Bra Size?

When it comes to looking effortlessly polished, nothing is more important than the foundations you wear underneath your clothes. A perfectly fitted bra not only elevates your silhouette but also makes every outfit from a silk blouse to a cashmere sweater—look and feel more luxurious. Yet, according to industry experts, over 70% of women are wearing the wrong size.

Here’s your quiet luxury guide to measuring your bra size at home, plus the best affordable luxury lingerie brands that offer the perfect balance of fit, comfort, and understated elegance.

Step 1: How to Measure Your Bra Size

You’ll need a soft measuring tape (and ideally, a mirror to check positioning).

1. Stand straight, wearing a non-padded bra or no bra.
2. Wrap the tape snugly around your ribcage, directly under your bust.
3. Round to the nearest whole number. If you get an even number, that’s your band size. If odd, round up to the next even number. Example: 31 inches becomes a 32 band.

Step 2: Measure Your Bust

1. Place the tape around the fullest part of your bust—usually over the nipples.
2. Keep it comfortably fitted, not tight.
3. Round to the nearest whole number.

Step 3: Calculate Your Cup Size

Subtract your band size from your bust measurement:

• 1 inch difference = A cup
• 2 inches = B cup
• 3 inches = C cup
• 4 inches = D cup, and so on.

Example: Bust 36″ – Band 32″ = 4″ difference → D cup.

Step 4: Try, Adjust, Refine

Sizing is a starting point, not a final verdict. Different brands vary, so try on multiple styles. Look for:

• Underband lying flat and snug (no riding up)
• Cups smooth with no spillage or gaping
• Straps supportive but not digging in

Affordable Luxury Lingerie Brands Worth the Investment

These labels combine premium fabrics, timeless design, and exceptional fit—without the four-figure price tag.

2. & Other Stories – Surprisingly good for lingerie, with chic lace and mesh designs that feel Parisian at heart—at a price point that allows for a top drawer refresh.

3. Skims – Kim Kardashian’s brand is proof that minimal, buttery-soft pieces can still look expensive. The Fits Everybody collection offers everyday bras that feel invisible under clothing.

4. Bluebella – London-based and loved for its architectural lacework, Bluebella’s pieces bring a modern twist to quiet luxury lingerie.

How to Measure Your Bra Size

Once you’ve found your perfect size and shape, consider buying multiples in your most-worn colours (nude, black, soft blush) so you always have a flawless foundation for your outfits. Just like a great white shirt or perfectly tailored trousers, a beautifully fitted bra is a quiet luxury essential because confidence always starts underneath.
