Japanese sizes follow the JIS standard and run about one size smaller than Indian sizes. Women's number sizes go 5, 7, 9, 11, 13, 15: a 86 cm bust is Japanese 11, which is Indian S. Men's sizes use S, M, L, LL and 3L by chest: a 96 cm chest is Japanese L, about Indian M. Japanese shoe size is just your foot length in cm.
