Transparent fabric? Absolutely (5)
I believe the answer is:
sheer
I believe this is a double definition.
'transparent fabric?' is the first definition.
(I've seen this before)
'absolutely' is the second definition.
(sheer can mean 'absolute')
(Other definitions for sheer that I've seen before include "Gossamer or precipitous" , "Diaphanous, filmy" , "sudden change of direction" , "Simple" , "transparent fabric" .)
