Sauce getting on clothes (8)
I believe the answer is:
dressing
I believe this is a double definition.
'sauce' is the first definition.
(I know that dressing is a type of sauce)
'getting on clothes' is the second definition.
(dressing means putting clothes on)
(Other definitions for dressing that I've seen before include "Putting clothes on" , "clothing" , "Sauce for salad etc" , "the early-morning routine" , "French or vinaigrette, say" .)
