Can I wear a sequin dress to a semi-formal wedding?
So, can you wear sequins to a wedding? Yes! Sequins are no longer just for evening gowns but are appearing on even casual outfits.
Semiformal clothes for a middle school dance may include a short dress with sequins at the neckline or all-over glitter.
In general, we don't recommend wearing jeans for any type of wedding (even the most casual weddings, unless the couple explicitly allows denim), and especially not for a semi-formal dress code. Opt for dress pants or khakis instead, paired with a blazer or suit jacket and tie.
Glitter, Glitter, Glitter Everywhere
Save the sparkles for the bachelorette party or another Saturday night on the town. Avoid wearing anything too shimmery or distracting. All eyes should be on the bride, and your disco-ball-looking dress may ruin her big moment to shine.
Embellishments like swishy fringe, lace and sequins are great for amping things up. Avoid cotton sundresses unless you can zhuzh them up with really fancy accessories like sparkly earrings or shiny new shoes.
Sure, they're shiny and jazzy, but they don't have to be tacky. In fact, sequins can look extremely chic when styled in a modern way.
Semi formal wedding attire sits at the sweet spot between understated dressy and elevated casual. It's also commonly referred to as “dressy casual” — which can be viewed as a weekend version of business casual. Think: flowy dresses, simple suit jackets, and timeless silhouettes.
A simple go-to for Christmas party dressing, sequins can be seen everywhere over the festive season. Dresses, tops, skirts and shoes, there is no fashion items that is safe from them. So why just reserve them for one month a year.
Floor-length gowns are beyond what the semi-formal dress code requires. Women following this directive might opt for a cocktail dress or a polished set. Semi-formal also translates to shorter hemlines, bold prints, or elevated separates like a festive top paired with tailored dress pants.
Many weddings require guests to dress in semi-formal attire. As such, selecting an ensemble needn't be complicated. To plan a stylish semi-formal wedding outfit, choose between a knee-length, midi or maxi dress in a comfortable yet chic style.
Is semi-formal and cocktail attire the same?
Cocktail. A small step above semi-formal, though not as formal as black-tie optional or black-tie, cocktail attire is a popular dress code choice. It's a balance between elegant and comfortable and typically more formal than a day wedding but more casual than a night celebration.
When the Attire is Semi-Formal or Cocktail Attire. If you're wondering, "Can you wear black to a wedding that has a semi-formal or cocktail attire dress code?" the answer is yes. Especially if the ceremony starts after 5PM, darker colors are encouraged; while lighter colors are appropriate if the ceremony starts later.

Too-sparkly metallics
Similar to wearing white, it will be seen as trying to steal the spotlight—not cool. However, if the wedding you're attending is formal or black-tie, sparkly gowns are usually okay—just don't go too overboard and wear something that could be construed as a wedding dress.
LACE AND SEQUINS.
In my humble opinion, the best way to wear lace and sequins is together. Opt for a mismatched option like any of the following bridal parties (1, 2, 3) or go for a semi-matched look like the very first picture on this post. More on bridesmaids, here: Fabulous Bridesmaid Gifts.
A plain white dress or white top and skirt are not generally acceptable, particularly in any formal style. Avoid ivory, off-white and light beige, too. However, it is okay to wear a patterned outfit that includes other colors along with white.
The staff suggests that if a wedding is taking place at 4 p.m. or 5 p.m., you should wear something that easily transitions from day to night; any ceremony after 6 p.m. should be strictly cocktail.
