They invest in furniture (8)
I believe the answer is:
dressers
'furniture' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for dressers that I've seen before include "ones employed backstage" , "Chests of drawers" , "Wardrobe assistants" , "Sideboards" , "They are found in theatres and in kitchens" .)
