Please measure wearing the bra you are most likely to wear when using this shirt. Be aware that different bras will give different chest measurements. When taking your measurements it is helpful to do it with a friend. Measure with only a bra (or bare chested when no bra is worn) and underwear on, stand relaxed with feet slightly apart (how you would naturally stand).
The lighter weight the fabric the more flowy the top. Different fabrics will have a different drape.
