If you want to invite all eyeballs in the party, then a cozy outfit can only help you in achieving your mission.

True, mix-n-match all always in.  But this only feature makes it stand away from party profile. Personally speaking, a dress devoted for party purpose should have one single shade, preferably, black at night, white in morning and can try other unusual shades in the day-time.

Accessories: It should be bold and loud to say everything on your behalf.
High-heels: Carrying heels is mandatory to step-in parties.
Make-up: It should be inversely-proportional with the color of the dress
