Yes there are "leggings" too, in the first part of the verse: As I hear it, the whole verse is:

"I met a little flaxy haired girl one day,
good morning little flaxy haired girl I did say,
good morning little beggarman and how do you do,
with your rags and your bags and your old rig-a-doo
I'll buy a pair of leggings and a collar and a tie,
and a nice young lady I will fetch bye and bye,
I'll buy a pair of goggles and I'll colour them blue,
and an old-fashioned lady I will make her too!"

A variant of the last line is "and that nice little lassie, I'll be her lover too!"
