Underwear designers (7)
I believe the answer is:
drawers
I believe this is a double definition.
'underwear' is the first definition.
(type of underwear)
'designers' is the second definition.
(I've seen this before)
(Other definitions for drawers that I've seen before include "Could be a chest of them but they're worn lower down" , "Knickers" , "designers" , "Undergarments" , "Underwear (for artists?)" .)
