Here's How to Ace a Semiformal Dress Code Like a Celebrity
If you've ever wondered what to wear to a semiformal event, I'll let these celebrity outfits do the talking.
A semiformal dress code always sound simple until you actually have to get dressed for it mainly because it lands right in the middle of two popular dress codes. Cocktail? Hmm, not quite. Black tie? Yes, but more pared back. Whenever I'm confused (which is often), I look to the celebrities who somehow make semiformal look like a personality trait. Alexa Chung, for example, arrived at the Burberry show in an outfit so perfectly calibrated it made me rethink everything I thought I knew about easy dressing.
After studying more red carpets, fashion-week arrivals, and event photos than I'd like to admit, I've identified the patterns. Zoë Kravitz leans into minimalism, Tracee Ellis Ross always brings sculptural silhouettes, Hailey Bieber does the clean and polished thing, and Paloma Elsesser proves structure and softness can coexist beautifully. Below, I break down exactly what makes each look work and how you can re-create them without needing a stylist on speed dial.
Zoë Kravitz
A lace slip dress with a fur coat on top makes for the perfect example of understated glamour. It feels all dressed up without crossing into the black-tie category.
Tracee Ellis Ross
Now, if someone tells you that you can't get away with shorts at a semiformal occasion, just show them this photo of Tracee Ellis Ross, and they'll be thoroughly convinced.
Ashley Graham
A knit dress always makes a big statement but doesn't necessarily work for a black-tie affair. That's why this one worn by Ashley Graham would be my dream attire for a semiformal night out.
Alexa Chung
People often ask me what outerwear is appropriate to wear at a semiformal event, and I can't rave enough about the power of a trench coat. This staple naturally elevates any look in seconds and pairs very well with a good pair of heels.
Hailey Bieber
Bieber is a woman who chooses to wear color only on special occasions. She's more likely to be caught in an LBD than a bright-green minidress. That's why I feel this photo defines semiformal attire—this is a dress code that encourages everyone to have some fun.
Paloma Elsesser
Here's more proof that semiformal doesn't mean you have to wear a dress. This power-dressing ensemble that consists of a silk top and black pants would be a great move, especially for a business-forward event.
