The most formal of all wedding dress codes is "white tie". Although, not very common they still exist. When dressing for this occasion think of all those fancy White House dinners Olivia Pope attends.
What to wear: Floor length dress in fall colors, paired with an open toe suede heel. Grab your rhinestone clutch and earrings and you are set to go.
Next to "white tie" will be "black tie" or "formal". Usually this pertains to night weddings and will be somewhat more laid back but still don't forget your very best.
What to wear: A short cocktail dress would be acceptable, all decked out in your best accessories. A dressy skirt with a top would also be an option if you didn't want to wear a dress.
SEMI FORMAL/DRESSY CASUAL
For a "dressy casual" wedding base your outfit decision on the time of the event. For a daytime event go for more neutral cool tones and for an evening time break out your darker hues.
What to wear: Instead of a cocktail dress, pair a dressy skirt with a dressy top and throw on some nude pumps.
Everyone's favorite type of wedding...casual! More than likely this will be an outdoor wedding. This means you want to dress for comfort and maybe warmth in case temps get a little chilly.
What to wear: Opt for a sweater dress with knee high boots and top it off with a stylish blanket scarf. This says "I still look good without much effort". Black jeans may be an option, but just because it's casual doesn't mean you are allowed to wear your ripped skinny jeans with a v-neck.
