It is the style in between casual and semi-formal attire. It's a dress code that calls for special event clothing that's trendy, relaxed and comfortable.

Think of the dress code as attire that is dressier than what you would wear to work, but not as formal as what you would wear to black-tie or formal events.

The term "dressy casual" can also appear in different forms on invitations; some couples may choose to write smart casual, upscale casual or fancy casual—but they all generally mean the same.

Allow the time of day, season and location of the event to guide your style choices. Putting effort into your outfit is respectful and courteous to the couple—so jeans, shorts, casual shirts and athleisure are all off limits.

For a daytime dressy casual wedding in warmer climate conditions, a cotton or light fabric shift dress is one choice. A button-down shirt tucked into a pair of chinos is also appropriate.

For weddings taking place in the evening, consider wearing a slightly more upscale outfit, like a midi dress with statement jewelry or a light-colored suit.

The venue can also provide inspiration for your dressy casual wedding attire. For example, for an event at a winery or upscale restaurant, your outfit should be on the dressier side (like a sleek jumpsuit or a blazer and slacks). Conversely, a relaxed backyard wedding is a place to wear a simple sundress or a dress shirt tucked into a pair of chinos.
