The size standards of underwear and bras may be slightly different. The following is an explanation of 3885C:

3885C is usually a style and model of a bra, and generally represents the cup size of a bra. , there are two possible explanations below:

- If you are referring to European bra size standards (such as France, Germany, etc.), the letter C represents the cup size, and 3885 is the model of this bra. A C cup is usually suitable for people with a difference of about 15cm between the bust and underbust. This is usually a medium or small cup size, but the exact size also depends on the manufacturer and the manufacturer's specific design.

- If you are referring to US bra sizing standards, 3885C would probably represent bust size. In U.S. sizing standards, brands and models are not generally related to cup sizes. C represents bust size, which generally ranges from 33 inches (approximately 84 cm) to 34 inches (approximately 86 cm).

Therefore, the specific cup size of the 3885C bra still needs to be different according to the specific size standards and brands. It is recommended that you refer to the size chart of the specific brand for confirmation.
