Sales rep, mortified to include retro child's suit (6)
I believe the answer is:
romper
'child's suit' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'sales rep mortified to include retro' is the wordplay.
'ROMPER' is hidden back-to-front in amongst the letters.
However, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for romper that I've seen before include "Young child's one-piece outer garment" , "Child's onesie" .)
