8 Wedding Dress Codes and What They Really Mean

Casual

What it means: While Bingham would go as far as to say that a "casual" wedding could be on the same tier as a night out or fancy brunch, you should still approach it with grace.

"I wouldn't go so far as to break out the basketball shorts and flip-flops," she said.

What to wear: For a daytime casual wedding, Bingham recommended an airy linen set or dress or an easy button-up and dark beige shorts. For a nighttime casual wedding, opt for longer pants or a dress.

"Wear something you'd wear meeting your significant other's parents for the first time," Bingham added. "It may be a casual wedding, but you still want to look nice for the happy couple."

Semi-Formal

What it means: In short, Bingham defined a "semi-formal" wedding dress code to be "just a notch below cocktail." You want to look nice, like you're going to a fancier restaurant for dinner, but in a way that's a little less buttoned-up.

What to wear: As far as fabrics, Bingham said traditional fabrics like silk are still in play, but you can bring your hemline shorter than knee length if you like.

"I'd also recommend a suit over a button-down and pants, but feel free to experiment with colors and fabrics," Bingham added, noting if you want a suave open-collar look, you'll want to ditch the tie.

Cocktail

What it means: Cocktail attire can be tricky to navigate. Bingham described it as "what Bond Girls dress in the first time James Bond spies them from across the restaurant." It falls somewhere between semi-formal and fully formal.

What to wear: Bingham said either a sleek suit or dress that falls knee length or lower is a safe bet when you're dressing according to cocktail wedding dress codes. A little black dress is always a classic, but monotone colors in materials like lace or chiffon will work as well.

Formal

What it means: The upside of formal weddings is that they generally aren't as strict as black tie affairs when it comes to guest attire. The downside is there isn't much guidance on what to wear other than to avoid anything casual because, well, it's a formal event.

What to wear: Bingham said long dresses in deep colors like mauve, emerald, or navy are most often associated with formal weddings.

"Fabrics like silk and crepe are always great [and while] a full tux isn't necessary, a crisp suit and tie are recommended," she added.

Beach Formal

What it means: A popular wedding dress code in coastal towns, Bingham described the concept perfectly when she says the couple is essentially saying, "We want you all to dress to the nines, but we also acknowledge that we're going to be on a literal beach."

What to wear: If you plan to suit up, Bingham suggested opting for a light color and linen fabric instead of wool-gray. Bright dress colors, she noted, are also welcome, including burnt yellows, soft pinks, and fun oranges.

Black-Tie Optional

What it means: You're still fancy, but suit-wearers have some leeway.

What to wear: According to Bingham, black-tie optional means virtually nothing if the plan was always to wear a nice dress. Instead, black-tie optional is essentially calling out suit wearers. 

"It means a tux and bow tie is encouraged but not necessary," Bingham said. "Formal suits and ties are acceptable."

Black-Tie

What it means: In one word: Fancy. You'll want to pull out all the stops for this one — heels, gowns, full tuxedos, the whole nine.

What to wear: For the dress wearers, Bingham said a black-tie wedding dress code calls for something floor length. 

"You shouldn't be able to see more than the toe of your shoe when you walk," she noted, adding that suit-wearers are expected to swap for a full-on tux. "Since it's black and not white-tie, you can opt out of the cumberbund if you'd like, but it's highly encouraged."

White-Tie

If you're going to a white-tie wedding, don't expect to see anything less than floor-length gowns and black jackets (or coats with tails). The most formal of wedding dress codes, now is your chance to live out your royal dreams with ball gowns in luxurious fabrics like silk and brocade. Opera gloves wouldn't hurt either.
