Size Guide

Size Guide

Use the charts below to help find your best size. The measurements shown are body measurements, not garment measurements.

Fit may vary depending on the style, fabric, stretch, cut, and manufacturer. Please also review the product description and any product-specific sizing information before placing your order.

Choosing between two sizes?
We recommend selecting the larger size for a more comfortable fit, especially when the product is described as fitted or has little stretch. Product-specific measurements and fit notes should always take priority over this general guide.

How to Measure

For the most accurate result, wear lightweight clothing or undergarments and use a soft measuring tape. Keep the tape level and comfortably fitted without pulling it too tightly.

1
Bust

Measure around the fullest part of your bust. Keep the measuring tape level across your back and comfortably relaxed.

2
Waist

Measure around the narrowest part of your natural waistline, usually above the belly button and below the rib cage.

3
Hips

Stand with your feet together and measure around the fullest part of your hips and seat, keeping the tape level.

Fit Tips

  • Compare your body measurements with the chart rather than relying only on your usual letter size.
  • When your measurements fall into different sizes, select the size that corresponds to the largest measurement.
  • For fitted dresses, jumpsuits and non-stretch fabrics, pay particular attention to the bust, waist and hip measurements.
  • Stretch fabrics may provide additional flexibility, while structured fabrics may fit more closely.
  • Product-specific sizing information and model measurements shown on the product page should take priority over this general guide.
  • Shoe sizing may vary slightly by design, heel height, toe shape and manufacturer.
Measurements are intended as a general guide only. Actual garment dimensions and fit may vary between different products, fabrics, styles and production batches.
