Host not right to appear in minimal attire? (5)
I believe the answer is:
thong
'minimal attire?' is the definition.
(skimpy underwear)
'host not right' is the wordplay.
'host' becomes 'throng' (both can mean a large group of people).
'not' indicates named letters should be taken away.
'right' becomes 'r' (common abbreviation).
'throng' with 'r' taken away is 'THONG'.
'to appear in' acts as a link.
(Other definitions for thong that I've seen before include "Skimpy garment" , "article of clothing" , "Leather strip fastener" , "Sandal" , "Thin leather strip" .)
