Has girly twirls using bright colours (8)

I believe the answer is:

garishly

I'm a little stuck... Click here to teach me more about this clue!

'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" .)

I've seen this clue in The Independent.
