What is is 38b bra size big?

As an AI language model, I do not have personal opinions or viewpoints, but I can provide some general information about the 38B bra size.

The size 38B bra is considered a medium to large cup size. It means that the band size is 38 inches and the cup size is B. The cup size measurement depends on the difference in inches between the bust measurement and the band measurement. A difference of 2 inches is a B cup size.

However, it is important to note that bra sizes are highly personal and dependent on a variety of factors such as genetics, weight, and body shape. What one person considers "big" or "small" can vary greatly from another person's perspective. Ultimately, the most important thing is to find a bra that fits well and provides adequate support and comfort for your body.
