HOW TO MEASURE Bust/Chest - Start by placing a measuring tape around the largest part of your bust/chest. The tape should be flat but not too snug. This is the most important measurement for determining your shirt size SizeChestWaistHipS35-3729-3236-39M37-4132-3539-42L41-4435-3842-46XL44-4838-4346-502X48-5343-4745-513X53-5847-5248-51 TOPS FINDING THE RIGHT FIT:For shirts, the most important measurement in determining your correct size is your bust/chest measurement. The shirt should fit snugly around the bust/chest, so that your weapon stays firmly in place and doesn’t bounce around when you move. If you order the shirt to fit your bust/chest, the rest of the shirt will stretch to accommodate a wider mid-section, and lightly hug a smaller midsection.
