For attending an opera in the afternoon, you should wear dress slacks and a dress shirt if you are a male. A female should wear a casual dress.
It depends on what kind of dress it is. If it is a fancy dress then you should wear gold or silver. If the dress has ruffles then you should wear chunky bits of rock, beads, wood, or bone. If the dress is plain then you should wear pearls or white beads.
Those are my measurements and i wear a size 4 dress when the dress has a full skirt and a 6 when the skirt is straight.
Size 8???

If you're ever in doubt, wear a dress.
