Chest circumference is genetic influenced by the average band size comes in at around 30", given 4'11" is ~5" beneath average assuming this is not a naturally broad woman (even when low bf%) it's sasfe to assume it'll be closer to 28-29" most chunky women come in at atleast 34-40" underbust and a C at those sizes would be equivalent to an F/G/H at 28" by actual breast volume
