Pedestrian is for it, I see (7)
I believe the answer is:
prosaic
'pedestrian' is the definition.
('prosaic' can be a synonym of 'pedestrian')
'for it i see' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'it' becomes 'sa' (old-fashioned abbreviation for sex appeal).
'see' becomes 'c' (the word for the letter, according to Chambers).
'pro'+'sa'+'i'+'c'='PROSAIC'
'is' is the link.
(Other definitions for prosaic that I've seen before include "Ordinary - not poetical" , "Banal" , "Commonplace, unromantic" , "Poetry would not be so" , "Dull (writing)" .)
