Formal summer wedding attire can encompass both white tie and black tie dress codes. Generally, you can never go wrong with a well-tailored tuxedo or glamorous long gown in material like chiffon or crepe.

These days, though, the term "formal attire" can also mean a dress code that's slightly less formal than black tie or black tie optional. This means that a tuxedo or floor-length gown might not be required, but the event is still formal enough for one to be appropriate.

(Pro tip: If you aren't sure how formal to dress, always choose the more formal option.) Elements like a high-neckline, one-shoulder sleeve or a printed pocket square can all make your formal outfit great for summer.

Elevate your ensemble with accessories like statement earrings, a bold headpiece, or luxe loafers (sans socks!) to complete the look.

Choosing what to wear to a summer wedding at the beach or a seaside venue comes with even more factors to consider. Opt for garments made of breathable fabrics and unfussy accessories like flat sandals, sturdy block heels or boat 

shoes that will stand up to warm weather and uneven terrain. This summer wedding attire also opens up the door to a world of possibilities when it comes to prints; palm patterns, color blocking, oversized florals and rattan textures are all ideal elements

of beach formal summer wedding attire. You might even consider wearing white bottoms with a contrasting blazer for the ultimate coastal look, "White pants embody summer and add an elegant touch to any look," Harmeling suggests.

"Pair them with a darker jacket for contrast or a lighter jacket for true beach vibes."

Depending on the time of the event, you'll want to dress somewhere between formal and casual for a semi-formal summer wedding. Wear darker, more formal hues for an evening soiree; opt for light colors and fabrics for daytime nuptials.

Keep in mind that semi-formal still has the word "formal" in the description, so you'll still want to look elegant and put together. Sure, you can keep your ball gown or tuxedo at home, but avoid dressing like you're going to a low-key family barbeque.

Breezy midi dresses and suits in alternative colors like dusty blue or forest green are all great options for a summer wedding with this summer dress code.

Generally, casual wedding attire means just about anything goes—but denim, shorts and tank tops are probably not appropriate unless they're specifically noted as acceptable. Regardless of how casual the summer wedding may be, it's still best to skip 

the jeans and flip-flops to be sure you're appropriately dressed for the occasion. For the purposes of wedding wear, assume this dress code means business casual to be on the safe side. Consider something like a jersey mini dress, or chinos and a polo shirt.
