Sizing

Finding Your What Katie Did Size

Sizing shouldn’t be mysterious. Start by taking your bust, waist and hip measurements, then compare them with our body measurement chart below.

This chart below shows the basic body measurements our UK dress sizes are cut to. It is a useful starting point rather than a finished-garment size chart. Most of our lingerie contains stretch, while non-stretch garments include ease to allow for movement and comfort.

Because fabrics, construction and the intended fit vary from one design to another, we include the exact measurements and specific sizing advice for every garment in its product description. Always check these details before choosing your size, even if you have bought from us before.

How to Take Your Measurements

For the most accurate result, measure yourself over well-fitting lingerie rather than clothing. Keep the tape measure level around your body and measure firmly.

Bust

Measure around the fullest part of your bust. Keep your arms relaxed and make sure the tape remains level across your back.

Waist

Measure around the narrowest part of your natural waist. This is usually above your belly button and below your ribcage.

Hips

Stand with your feet together and measure around the fullest part of your hips and bottom. Check that the tape is level all the way around.

If your measurements fall between sizes, use the individual garment measurements and fitting notes in the product description to decide which size will suit you best.

Before You Choose Your Size

The chart below describes the body measurements each size is designed around. It does not show the measurements of the finished garment.

A stretchy suspender belt, a structured girdle and a non-stretch skirt may all fit differently, even when they carry the same size label. That is why every product description includes measurements and advice specific to that garment.

For the best fit:

Take your current body measurements.
Read the sizing information in the individual product description.
Give the product-specific measurements priority when making your final choice.

If you are still unsure, our team will be happy to help you compare your measurements with the garment before you order.
