'skimpy garment' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'two artists sketch queen getting in' is the wordplay.
'two' indicates the doubling of some letters.
'artists' becomes 'RA' (Royal Academy of the Arts).
'sketch' becomes 'skit' (short comedy performance).
'queen' becomes 'r' (abbreviation for regina, e.g. in ER ).
'getting in' means one lot of letters goes inside another.
'ra' duplicated is 'rara'.
'skit' enclosing 'r' is 'skirt'.
'rara'+'skirt'='RA-RA SKIRT'
