Dash of red seen below bowl on side of armoire (7)
I believe the answer is:
panache
'dash' is the definition.
(both can mean style or flair)
'red seen below bowl on side of armoire' is the wordplay.
'red' becomes 'che' (Che Guevara the Marxist revolutionary).
'seen below' means one lot of letters go next to another (some letters go below others).
'bowl' becomes 'pan' (I've seen this in other clues).
'on' says to put letters next to each other.
'side of' says to take the initial letters (the letter from one side of the word).
The initial letter of 'armoire' is 'a'.
'pan'+'a'='pana'
'che' put after 'pana' is 'PANACHE'.
'of' is the link.
(Other definitions for panache that I've seen before include "Flamboyant confidence" , "Great style" , "Sense of style, swagger" , "Distinctive elegance" , "A confident stylish manner" .)
