Unfortunately, partner's tan is see-through (11)

Ross

I believe the answer is:

transparent

'see-through' is the definition.
('transparent' can be a synonym of 'see-through')

'unfortunately partner's tan' is the wordplay.
'unfortunately' is an anagram indicator.
'partners'+'tan'='partnerstan'
'partnerstan' with letters rearranged gives 'TRANSPARENT'.

'is' acts as a link.

(Other definitions for transparent that I've seen before include "Obvious - ingenuous" , "Lucid - evident - clear" , "Frank" , "poor at lying" , "Open" .)

I've seen this clue in The Times.
