Ken’s original red shorts with white lines. there are two types of his red shorts with lines, code type line and tape type line. he wore these in 1961.
I guess ‘white-tape shorts’ are less numerous. I haven’t found any outfits and accessories with the exact same ‘white-tape’ so far.
‘white-code’ seems to have been used for Barbie fashion 1959-61 #966 Plantation Belle first. also used for Barbie fashion 1962-63 #937 Sorority Meeting hat.
