Has girly twirls using bright colours (8)

I believe the answer is:
garishly
'using bright colours' is the definition.
I can't judge whether this definition defines the answer.
'has girly twirls' is the wordplay.
'twirls' is an anagram indicator (I've seen 'twirling' mean this).
'has'+'girly'='hasgirly'
'hasgirly' anagrammed gives 'GARISHLY'.
Can you help me to learn more?
(Other definitions for garishly that I've seen before include "In a cheap and flashy way" , "in a gaudy way" , "gaudily" .)
