Solid figure in Capri smeared (5)
I believe the answer is:
prism
'solid figure' is the definition.
(I've seen this before)
'in capri smeared' is the wordplay.
'in' indicates a hidden word.
'PRISM' is hidden within 'capri smeared'.
(Other definitions for prism that I've seen before include "Refracting glass" , "Triangular piece of glass to deviate a beam" , "Light-bending glass" , "Light-splitting device" , "Type of polyhedron" .)
