What Is a 20C Bra Size? Understanding Fit & Shape
A 20C bra size in Australian sizing means a size 20 band (90cm underbust measurement) with a C cup. This follows the Australian bra sizing standard, where the band size is based on the measurement around your ribcage and the cup size is determined by the difference between bust and band measurements. A 3cm difference typically indicates a C cup.

- Bust size: Measure around the fullest part of your bust. Ensure the tape is level and not too tight.
