Chest is usually the best size predictor for tops. However, if your hip measurement is larger, consider buying the size indicated for your hips.
Chest — Relax your arms, then measure around the fullest part of your chest
Waist — Bend slightly to one side to find your natural waist. This will be the crease created from bending. Then, stand erect and measure around your body at the crease points.
Hips — Stand relaxed with feet shoulder-width apart. Now, measure around the fullest part of your hips and seat.
