Dress up bride, more excited (9)
I believe the answer is:
embroider
'dress up' is the definition.
(thesaurus)
'bride more excited' is the wordplay.
'excited' indicates an anagram.
'bride'+'more'='bridemore'
'bridemore' with letters rearranged gives 'EMBROIDER'.
(Other definitions for embroider that I've seen before include "Sew; embellish" , "Elaborately sew" , "Ornament with needlework" , "Do decorative needlework" , "stitch" .)
