How to Choose Your Size

Start With Body Measurements

Compare your body measurements to the chart, not just the size you usually wear. Different product fits may feel closer or more relaxed.

Check the Product Details

Always review the product page for fit notes, style details, fabric stretch, inseam options, and any item-specific sizing guidance.

Measuring Tips

  • Chest or bust: Measure around the fullest part of the chest or bust while keeping the tape level.
  • Neck: Measure around the base of the neck, allowing enough room for a comfortable fit.
  • Sleeve: Measure from the center back of the neck across the shoulder and down the arm, or follow the product-specific sleeve guidance.
  • Waist: Measure around the natural waistline or the waist position noted for the product category.
  • Hips: Measure around the fullest part of the hips while standing naturally.
  • Inseam: Measure from the center of the crotch seam to the bottom of the leg opening.

Fit Notes & Between-Sizes Advice

If you are between sizes, choose based on the fit you prefer and the way you plan to wear the item. For layering pieces, some customers may prefer the larger size. For a trimmer look, the smaller size may feel more fitted.

For pants and shorts, compare both waist and hip measurements. For tops, compare chest or bust first, then review neck and sleeve measurements where relevant. For suits, select the jacket size first and review the matching pant waist guidance before ordering.
