02

Waist

Measure at your natural waistline above hip bones, with one finger of ease.

03

Hip

Measure around the fullest part of your hips, about 7–9 inches below the waist.

04

Neck (shirts)

Wrap around the base of the neck. Allow one finger of ease; round to the nearest half-inch.

05

Foot Length

Trace your foot on paper and measure heel to longest toe. Use the larger foot.

06

Height

Stand barefoot against a wall. Measure from the floor to the top of your head.

Shopping Tips

  1. 01Sizing varies between brands — always check the brand's own size guide first.
  2. 02When possible, try garments on in-store for the most accurate fit.
  3. 03For stretch fabrics you may size down; for structured pieces, use your measured size.
  4. 04If your measurements fall between two sizes, consider the garment's cut and fabric stretch before deciding.
  5. 05Keep receipts and tags until you're sure of the fit.
  6. 06Always defer to the brand's own size guide when one is available.
