'blouse' is the definition.
(I've seen this before)

'clothes laid out one wears' is the wordplay.
'clothes' becomes 'garb' (garb is a kind of clothes).
'laid out' becomes 'aldi' (I can't explain this - if you can you should believe this answer much more).
'one' becomes 'i' (Roman numeral).
'wears' means one lot of letters goes inside another.
'garb'+'aldi'='garbaldi'
'garbaldi' going around 'i' is 'GARIBALDI'.

'from' acts as a link.
