Ship off clothes tried out where culture's displayed (5,4)
I believe the answer is:
petri dish
'where culture's displayed' is the definition.
(as in microbial culture)
'ship off clothes tried out' is the wordplay.
'off' is an anagram indicator.
'clothes' indicates putting letters inside (some letters clothe or cover others).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'ship' with letters rearranged gives 'pish'.
'tried' is an anagram of 'etrid'.
'pish' placed around 'etrid' is 'PETRI DISH'.
(Other definitions for petri dish that I've seen before include "Type of plate used for culturing bacteria etc" , "Container for growing cultures" , "Shallow bowl used to culture bacteria -- priest hid (anag)" , "Shallow plate for lab study" .)
