How It Works
Uses a stated one-inch cup-difference convention: rounded(bust−chosen band), with 1=A, 2=B, 3=C, 4=D, 5=DD, 6=E, 7=F, 8=FF, 9=G, 10=GG, 11=H, 12=HH, 13=J, 14=JJ, 15=K.
Choose a comfortable, correctly fitted even-numbered UK band first. This tool does not automatically add inches to an underbust measurement. Brand patterns and cup sequences vary; this is a starting estimate for trying on.
