Hosting queen, fetch up rug (6)
I believe the answer is:
peruke
'rug' is the definition.
(type of wig - rug can mean a wig)
'hosting queen fetch up' is the wordplay.
'hosting' is an insertion indicator (inserted letters are welcomed in or hosted).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'fetch up' becomes 'puke' (both can mean to vomit).
'er' placed inside 'puke' is 'PERUKE'.
(Other definitions for peruke that I've seen before include "Old fashionable wig" , "Ancient wig" , "18th-century wig" , "Periwig" .)
