slang etymology, of "deriving" the term, in 
the sense used, from duds (formerly sometimes 
spelled dudes : see dud), clothes, in the sense of 
'fine clothes'; and the connection, though ap- 
parently natural, is highly improbable.] A fop

ments of dress, speech, manners, and gait, and 
a serious mien ; nence, by an easy extension,

cessive refinement of fashion in dress.
