Old boy found in drawer tattered clothing (8)
I believe the answer is:
wardrobe
'clothing' is the definition.
(wardrobe is a kind of clothing)
'old boy found in drawer tattered' is the wordplay.
'old boy' becomes 'ob'.
'found in' indicates putting letters inside.
'tattered' indicates anagramming the letters.
'drawer' with letters rearranged gives 'wardre'.
'ob' put inside 'wardre' is 'WARDROBE'.
(Other definitions for wardrobe that I've seen before include "Tall furniture for storage of clothes" , "Item of bedroom furniture" , "Costume department" , "Complete set of clothes, or their container" , "storage place" .)
