Aside from absolutely, under no circumstances, never, ever, ever wearing white, the rules of what to wear as a wedding guest can be tricky. That trickiness is multiplied when a seemingly nebulous dress code like semi-formal or cocktail attire comes into play. Thankfully, the question, "what is semi-formal wedding attire?" has very chic answers that are likely already sitting in your wardrobe.

According to fashion stylist and Pretty Connected founder Lara Eurdolian King (who recently had a semi-formal wedding of her own, complete with seven outfit changes), the sky is the limit when it comes to putting together a semi-formal wedding 'fit. "A 'semi-formal' outfit takes some of the pressure off," she says. "Semi-formal wedding attire could be designer (or not), vintage, and have lux fabrics and details, but often is more casual and playful, featuring lighter fabrics, and in a mix of hemlines."

What does that mean exactly? Steer clear of anything that might double as a beach cover-up or that you'd toss in the wash on a regular cycle, along with jeans and yoga pants. In other words, semi-formal can be comfortable, but it should also be elevated. According to Eurdolian King, you can wear "anything from a long slip dress to an over-the-knee situation, two-piece or even pants."

A Statement Jumpsuit

Wondering where to wear the killer jumpsuit that's been languishing in the back of your closet? The answer is definitely a wedding that calls for semi-formal wedding attire. The few exceptions to this styling option would be if the jumpsuit is particularly revealing (in which case save it for a night out on the town), pale enough to read as white in certain lighting or photographs, or if it features lots of denim.

Look For Luxe Details

A semi-formal wedding outfit doesn't have to be overly complicated or uncomfortable, but it should be elegant. Eurdolian King recommends picking pieces that are fun to wear while still containing luxurious details. Think rich fabrics, bold prints, and visually exciting design elements. Velvet, pleating, and tasteful lace are all good options.

A Flirty, Romantic Dress

Have a dress that's too much for brunch but too casual for a black-tie event? The light, playful details on a romantic dress, like ribbons and ruffles, make it the perfect option for a semi-formal wedding.

Opt for Sharp Suiting

Suits are totally fair game for a semi-formal wedding, but be sure that the tailoring is top-notch. Semi-formal is light on the formal but does call for immaculate vibes. If you skip an ensemble starring a dress or skirt, you'll want it to fit like a glove so as not to read too casual.
