UK Bra Size Chart FAQ

1. How do I use this chart to find my exact UK bra size?

To find your exact size using the UK Bra Size Chart:

  1. Measure Your Band Size: Wrap a measuring tape snugly around your ribcage, just under your bust. Round this measurement to the nearest inch. This will give you your band size.
  2. Measure Your Bust Size: Measure around the fullest part of your bust, keeping the tape level. Round this measurement to the nearest inch.
  3. Refer to the Chart: Find your band size in the top row and your bust size in the left column. The intersection of these measurements on the chart reveals your UK bra size.

Example: If your band measurement is 34 inches and your bust measurement is 37 inches, use the chart to find your size, which should be 34C in UK sizing.

2. What is a 'Sister Size,' and how do I find it in the UK chart?

A sister size has a different band and cup size but offers a similar fit. For instance, if your UK size is 34C, you might also find that a 32D or 36B fits well, depending on the brand.

To find sister sizes:

  • Size Down in Band, Size Up in Cup: If you are a 34C, try a 32D.
  • Size Up in Band, Size Down in Cup: If you are a 34C, try a 36B.

Use the chart to locate your band and cup size, then check other sizes with similar measurements.

3. Which popular brands use the UK bra sizing system?

Many UK-based brands use the UK sizing system, including:

  • Marks & Spencer: Known for comfort-focused styles and diverse size options.
  • Bravissimo: Specializes in sizes for fuller busts.
  • Panache: Popular for support and structure.
  • Curvy Kate: Offers bras for various sizes and styles.
  • Freya: Known for fashionable designs and great fit options.
4. Why does my bra size vary between brands?

Although the UK sizing system is standardized, sizes can vary across brands due to differing design philosophies, materials, and cuts. Some brands focus on structured support, while others prioritize flexibility.

For the best fit, consider trying on your size in several brands or consult brand-specific size guides.

5. What should I consider before choosing a bra size based on this chart?

Body Changes: Weight changes, pregnancy, or age can affect your size. Measure regularly to ensure a good fit.

Brand-Specific Fit: Each brand may fit differently, so check reviews or try multiple sizes.

Fit Across Styles: Styles may fit differently; for instance, sports bras are generally snugger than balconettes.

Proper Measuring: Stand straight and avoid pulling the tape too tight or leaving it too loose when measuring.
