A WHITE DRESS
You know there’s always that one woman who shows up in ivory–and drives the bride to an early grave. At the very least, keep your fabrics in the taupe or blush territory, and save that white lace number for a graduation or estate party.
A PAIR OF BRAND-NEW STILETTOS
We know, it’s your one chance to get really dressed up. But remember: You will be walking from table to table and you will be dancing till midnight. If you haven’t adequately broken in those heels yet, you’re asking for trouble. Either make sure to wear them in beforehand or choose a more sensible pair from the start.
ANYTHING TOO REVEALING
Even if you think something looks good straight-on in front of the mirror, make sure to do a chair (and stairs) check. Weddings are a time of support–not a time for other guests to gossip about your Spanx line.
ANYTHING OUTSIDE THE DRESS CODE
You may have the fiercest little cocktail frock you’re dying to debut, but the dress code may be black-tie optional. And in that instance, you’re better off in a long gown (so you don’t have any chance of feeling underdressed).
