Size Guide
Built to fit. Engineered to last.
Sizing intimate apparel right is the difference between a piece you wear every day and a piece you return. We use UK sizing across all four products, with full body measurements in centimetres. Pick the size that matches your largest measurement.
How to measure.
- Bust: Measure the circumference of the fullest part of your bust.
- Underbust: Measure straight across, just under the bust band.
- Waist: Measure the thinnest part of your waist.
- Hips: Measure the fullest part of your hips.
- Height: Standing measurement, head to floor.
If you're between two sizes, size up for The Everyday, The Active, and The Brief. For The Form, order your usual size, the fabric stretches significantly when worn.

| Label | UK Size | Bust (cm) | Waist (cm) | Hip (cm) | Height (cm) |

| XL | UK 16 | 102 - 107 | 81 - 86 | 107 - 112 | 176 - 180 |
| XXL | UK 18 | 108 - 113 | 87 - 93 | 113 - 118 | 181 - 185 |
Note: L and XL share the same height range. The difference is in bust, waist, and hip, not body length.
Sizing between two?
For The Everyday, The Active, and The Brief: size up for comfort, size down for a more fitted look. For The Form: order your usual size, the fabric does the work.
Still unsure?
For bras (The Everyday and The Active): order both sizes if unsure, keep the one that fits, return the other. We cover unworn, unwashed pieces with tags attached.
For The Brief and The Form: pick the size that matches your measurements. The hygiene seal limits returns once the packaging is opened, so the size chart matters more for these two pieces.
