Take the numeric part of your everyday bra (eg. 36) and check it against the chart. This tactical bra is a compression garment. The feeling should be a firm, hugging, stabilizing security - not "tight". If you are full busted, DO NOT SIZE DOWN as you might have with other bra's, thinking that is what you would require to stabilize your chest. That is not necessary with this bra.

For customers with restricted arm or shoulder mobility, we do suggest sizing up one size for easier on/off.

If you are unsure about your correct measurement, simply measure around the largest part of your back around to your breast bone (above your breast area) and pull the tape tightly. Use that number.
