Let's start with the most formal of all wedding attire: black tie. Elevated and elegant is the name of the game here and it's an excuse to go all out, à la Laura Harrier in this gorgeous golden Staud gown with an embellished neckline. Check out the same style in black, featuring gorgeous shark-tooth chain straps.

Cocktail attire sits right in the middle of black tie and casual, so you'll want to look festive but not too formal. Heidi Klum nailed cocktail attire recently with a curve-accentuating Ronny Kobo dress, and this similar option from the label would pair perfectly with some party-ready accessories. Finally, there's the destination or beach wedding, which tends to be a more casual affair. There's a good chance you'll be spending extended periods of time on the sand or grass, making wedges or flat sandals a must. Nicky Hilton's pretty printed Alice + Olivia maxi would be great for this sort of event, and this likeminded dress is practically begging to be worn on the beach.
