What Not to Wear to a Wedding: 5 Outfit Mistakes Guests Should Avoid

Upon receiving a wedding invitation, it’s typical to immediately start thinking about logistics (and asking for time off from work) — but don’t let that split-second reaction sideline your consideration of a pressing issue: what to wear? There’s a lot to consider, from the dress code to how the weather will be and where you’re going and the time of day or year. But even when you’ve managed to whittle down your outfit choices, there are some sartorial missteps that could inadvertently violate years of wedding etiquette.

Yes, most women who are invited to a wedding manage to steer clear of anything that even slightly resembles a wedding dress. But then what about patterns that are too white? Or shoes that are not suitable for the terrain? To help steer clear of any fashion faux pas, wedding stylist Celeste Monroe, owner of Harper Lane Styling, reveals the most common errors wedding guests make with their attire, and how to dress in a manner that is respectful and event-appropriate.

Her biggest tip? “If you even have to ask whether something is appropriate, that’s typically a good sign,” Monroe says. “If you’re dithering, just do something else. You’ll feel more comfortable — and you won’t risk calling attention to yourself for the wrong reasons.”

Ahead, Monroe shares the five things she tells her clients not to wear as a wedding guest.

Anything That Looks Too White

The following cardinal top rule remains, and it's unless the couple has called for guests to wear white, steer clear. “Just no white unless it’s a themed wedding that specifically asks for it,” says Monroe. “But there are gray zones — literally. Florals or stripes with a white background can work fine, but again, it all depends on the couple’s vibe.”

Her test? Step back and squint. “If more than 25 percent of your dress is looking white from a distance, choose something else,” she recommends.

Even if your outfit seems glaringly nonbridal to you, expect some raised eyebrows. “Older guests, in particular, sometimes have feelings about wearing white to a wedding,” she says. “ Understand if you wear this you’ll be hearing some comments.”

Clothes That Don’t Recognize the Dress Code

Whether the pair asks for “garden chic,” “black tie” or something in between, it’s on you to respect the dress code. “There’s often a reason for it — maybe it’ s a reflection of the venue or it sets the mood for the day,” Monroe says. “Make sure even if you might not have the exact outfit, get as close as you can.”

And if you’re on a budget? Consider a rental service or borrowing from a friend. “If the invitation says black tie, the least you can do is wear a dark suit,” she says. “You don’t need to go buy a tux, but you need to respect the request.

Denim (Yes, Even Nice Denim)

However casual the wedding, jeans are not. “Even at less formal parties, denim does not fit in there,” Monroe says. “This is a moment that’s important for this couple — you don’t want to look like you’re going to a barbecue.”

That doesn’t mean you have to be stuffy. “Reach for an olive or taupe suit, a fun jumpsuit, or a midi dress with personality,” she recommends. “If you’re having a backyard or ranch wedding, you might be able to get away with a denim jacket — but even then, I’d go for a knit cardigan instead.”

The Shoes Didn’t Match the Scene

Comfort is the name of the game with shoes—but so is practicality. “If it’s on sand, grass or cobblestone, leave the stilettos at home,” says Monroe. “Listen to any hints that the couple gives. If they discuss block heels or flats, you should heed that.”

And please don't suffer in silence just to be taller. “If you can’t walk in four-inch heels, a wedding is not the place to try,” she says. “You don’t want to be that guest who takes a digger on the dance floor.”

An Outfit That’s Too Sexy

This one’s all about balance — and the venue. “If the ceremony is going to be held in a house of worship, it’s respectful to dress a bit more modestly,” Monroe says. “Even aside from that, you want to make sure not to take away from the celebration.”

Her advice? Emphasize one, not all. “If the dress is too short, choose a higher neckline. If you’re wearing a plunging top, aim for the bottom half to be more covered,” she says. “Make one good thing a feature, not everything at once.”

Final Thoughts

Weddings are happy affairs — and the best guest outfits imbue that sense of joy while respecting the couple’s wishes. “Dress consciously, and not just for style, but setting and people,” Monroe says. “You’ll feel more at ease, and you’ll also show that you care. That’s the real fashion win.”
