Dine out, having money, and blue (8)
I believe the answer is:
indecent
'blue' is the definition.
(thesaurus)
'dine out having money' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'having' means one lot of letters go next to another.
'money' becomes 'cent' (I've seen this before**).
'dine' anagrammed gives 'inde'.
'inde'+'cent'='INDECENT'
'and' acts as a link.
(Other definitions for indecent that I've seen before include "Offensive to common modesty" , "Lewd" , "Immodest, gross" , "Unbecoming, obscene" , "Unseemly" .)
