All measurements are approximate and meant as a general guide. If you’re between sizes, sizing up is usually the safest choice for comfort.
Bust: measure around the fullest part of your bust.
Waist: measure around your natural waistline (smallest point).
Hips: measure around the fullest part of your hips/seat.
Tip: corsets can fit more firmly than lingerie sets. If you prefer a less-snug feel, choose the larger size.
