Personal designer joins parade first (9)
I believe the answer is:
tattooist
'personal designer' is the definition.
'tattooist' can be an answer for 'designer' (I've seen this before). I'm not certain of the 'personal' bit.
'joins parade first' is the wordplay.
'joins' is a charade indicator (letters next to each other).
'parade' becomes 'tattoo' (I've seen this before).
'first' becomes 'ist' (ist resembles tst).
'tattoo'+'ist' is 'TATTOOIST'.
Can you help me to learn more?
(Other definitions for tattooist that I've seen before include "Skin artist" , "Skin decorator" , "Designer" , "Sort of marksman" , "permanent marker?" .)
