Compare a favourite piece.
The clearest way to compare clothing is to measure something you already like wearing, then use the same method on the product chart.
Tops
Lay the garment flat without stretching it. Measure across the chest just below the armholes, shoulder to shoulder, and from the highest shoulder point to the hem. Note whether it is a fitted, regular or relaxed piece.
Bottoms
Measure the waistband flat, the rise from crotch seam to waistband, the inseam and leg opening. Wear the same shoe type when deciding your preferred length.
Before ordering
Read the product’s own chart, fabric details and care notes. Do not equate body measurements with garment measurements unless the chart explicitly says to. When products are real, Highness will publish the measurement method used on each page.
