What to wear to a US wedding, by dress code
American wedding invitations use a handful of dress code phrases, and they are not always clear. Here is what each one means and what to wear, whether the wedding is in a New York ballroom or a Texas barn.
The dress codes, in plain words
| Dress code | What to wear | Skip |
|---|---|---|
| White tie | Formal floor-length evening gown | Short hemlines, casual fabrics |
| Black tie | Floor-length gown or very elegant formal jumpsuit | Cocktail dresses, daytime fabrics |
| Black tie optional | Floor-length gown, or a dressy midi or cocktail dress in a rich fabric | Casual dresses, flat casual sandals |
| Cocktail attire | Knee length or midi dress, or a dressy pants set | Jeans, sundresses, anything beachy |
| Semi-formal or dressy casual | A nice dress or skirt set, polished shoes | Tees, sneakers, very short hems |
| Casual | Sundress, skirt and nice top, dressy sandals | Anything you would wear to the gym |
Regional and venue notes
- Southern and country weddings often lean dressy, even outdoors. Florals and pastels are common in spring and summer.
- Beach and destination weddings call for lightweight fabrics, wedges or flat sandals, and a layer for the evening breeze.
- City weddings often run more formal and later in the evening. Dark and jewel tones are common, and black is widely accepted.
- Barn or rustic weddings suit midi dresses, block heels or boots, and a jacket for the evening.
What to avoid
- White, ivory and cream, which are reserved for the bride.
- The bridesmaids' exact color, if you know it.
- Anything you cannot sit, hug and dance in.
- Brand new shoes you have not broken in.
Dress for the weather
A summer wedding in Arizona and an October wedding in Vermont need very different outfits. Check the forecast a week out. Breathable fabrics and a light wrap suit heat. Long sleeves, a coat and closed shoes suit cold. For the in-between weeks of spring and fall, build your outfit in layers.
Shop your closet first
Most women own more event wear than they remember. Gather every dress you have worn to a dinner, party or wedding, and check each against the dress code table. Try it with different shoes, a different jacket and a different bag, and photograph the options. If you are traveling for the wedding, see how to pack a week with 12 pieces.

Start with what you already own
Most of the outfits in this guide are already hiding in your wardrobe. The hard part is seeing your clothes together. Photograph one outfit you already wear and Modebase picks out each piece for you. Then you can ask for outfits in the chat you already use, such as ChatGPT or Claude, and it answers from your own clothes. For example:
I am going to a black tie optional wedding in October in Chicago. Show me three outfits from my closet and tell me which one is the most comfortable for dancing.
Frequently asked questions
What is the difference between black tie and black tie optional?
Black tie expects a floor-length gown or equally formal outfit. Black tie optional is slightly more flexible, so a dressy midi or cocktail dress in a rich fabric is also fine.
What does cocktail attire mean for a wedding?
A knee length or midi dress, or a dressy pants outfit. It is dressy but not floor length.
Can I wear black to a wedding in the US?
Yes, black is widely accepted today, especially for evening and city weddings. Add color or sparkle with accessories.
What should I wear to a casual wedding?
A sundress, or a skirt with a nice top, and dressy sandals or flats. Keep it polished and avoid anything you would wear to the gym.
