Resembling or characteristic of a dandy; excessively concerned with fashion, appearance, and affected elegance.
From 'dandy' plus the adjective-forming suffix '-ish,' which has Germanic roots and means 'having the quality of.' This productive suffix allows English speakers to create numerous informal descriptive terms.
The '-ish' suffix is one of the most flexible in English—you can add it to almost anything to mean 'somewhat like' or 'kind of,' which is why English speakers love it for being non-committal and casual.
