Style of leotard that keeps one well-dressed (8)
I believe the answer is:
tailored
'well-dressed' is the definition.
Both the answer and definition are adjectives.
Maybe you can see an association between them that I don't see?
'style of leotard that keeps one' is the wordplay.
'style of' indicates anagramming the letters (I've seen 'style' mean this (style can mean to shape or design)).
'that keeps' is an insertion indicator (inserted letters are kept inside).
'one' becomes 'i' (Roman numeral).
'leotard' with letters rearranged gives 'talored'.
'talored' enclosing 'i' is 'TAILORED'.
Can you help me to learn more?
(Other definitions for tailored that I've seen before include "Suited to an individual" , "Made garments, suits perhaps" , "Fitted, well-cut" , "(Of clothes) fitted, well cut" , "Simple in line or design, suit perhaps" .)
