How to measure: For the most accurate fit, measure yourself in your underwear. Use a soft measuring tape and keep it snug but not tight. For chest measurements, measure around the fullest part of your bust. For waist, measure around the narrowest part. For hips, measure around the fullest part. For sports bras, measure your underbust directly under your bust where the band sits.
