10 AU/NZ cup letters, one page each
The letters this system writes, each with its own page.
AU/NZ band labels run from 6 to 38 in steps of 2. Each is the US and UK band minus 22, so 10 corresponds to US and UK 32. A band label names the band on a tag, not a body measurement; body ranges depend on the underbust method, add-4 method, or another method. One published chart gives bands in steps of 5 cm and says size 10 covers an underbust of 68 to 72 cm.
AU/NZ cup letters start at AA for a difference of less than 1 in, then run A, B, C, D, DD, E, F, G, H, I, J, K, L, M, and N, ending at a difference of 15 in. The listed differences between these endpoints are not all included. The letters match UK cups through F at 7 in, then use single letters from G at 8 in through N at 15 in.
Published charts disagree at a difference of 8 in: some give G and another gives FF. They also disagree at 10 in, where some give I and another gives GG. Example AU/NZ tags include 10A, 12B, and 14C; a US 34DD/E tag is listed as 12DD in AU/NZ labels.
