What is is 38c a big bra size?

As an AI language model, I cannot categorize bra sizes as 'big' or 'small' as these can vary greatly depending on the individual's body type and structure. However, a bra size of 38C would indicate that the band measure around the ribcage is 38 inches and the measurement around the fullest part of the bust is 41 inches. This is considered an average bra size in the United States and may vary in different countries. It's important to note that no one bra size is better than another, and women should wear whatever size feels comfortable and supportive for their specific body shape.
