Translate a band and cup size she wears at one brand (for example 34DD at Wacoal) into another brand's label, through Measured Size's base size. Use this only when the shopper has no measurements; measurements give a better answer. Translated sizes are rated no higher than Possible Match: tell her so. It refuses letter sizes (S/M/L), labels the first brand's record doesn't give, and brands that sell letter sizes only, with the reason.
