Gentleman from Wiesbaden said to need kitchen furniture stylist (11)
I believe the answer is:
hairdresser
'stylist' is the definition.
(synonyms)
'gentleman from wiesbaden said to need kitchen furniture' is the wordplay.
'gentleman from wiesbaden' becomes 'herr' (German equivalent to 'mister' - eg in Wiesbaden).
'said' indicates a 'sounds like' (homophone) clue.
'to need' says to put letters next to each other.
'kitchen furniture' becomes 'dresser' (dresser is a type of kitchen cabinet).
'herr' is a homophone of 'hair'.
'hair'+'dresser'='HAIRDRESSER'
(Other definitions for hairdresser that I've seen before include "Stylist" , "cutter?" , "Lock smith?" , "Coiffeur, coiffeuse" .)
