What is different between 34C, 34B and 34D bra size?

The main difference between 34C, 34B, and 34D bra sizes is the cup volume. In general, the band size (in this case, 34) represents the measurement around the ribcage, just below the breasts. The cup size, which is represented by the letters (C, B, or D), represents the difference between the band size and the measurement around the fullest part of the bust.

A 34B bra would generally have a smaller cup size than a 34C bra and a larger cup size than a 34A bra. A 34C bra would have a larger cup size than a 34B bra and a smaller cup size than a 34D bra. Finally, a 34D bra would generally have a larger cup size than both 34B and 34C bras.

However, it’s important to note that bra sizing can vary between different brands and styles. Additionally, other factors such as the shape and placement of the breasts can affect the fit of a bra, so it’s always best to try on different sizes and styles to find the best fit for you.
