What to Wear to a Cocktail Party 

The Best Occasionwear for Every Event - What to Wear to the Cocktail Party



Raise a glass to the upcoming party season in a statement dress, and pair your look with equally glitzy accessories to make an unforgettable entrance.

For unabashed partywear, look no further than 16 Arlington. 

Delicate pearl drops add regency flair to these statement earrings. 

Fairytale shoes that will keep you dancing long past midnight.

What to Wear to a Garden Party 

The Best Occasionwear for Every Event - garden party



Mirror your surroundings with a printed midi dress, which is always a fail-safe choice. 

A ditsy-printed sundress that you can easily wear for daytime picnics or dress up for evenings with gold accessories.  

A pillowy-soft cloud bag is the modern take on the traditional box clutch.

The most versatile accessory in your arsenal.

Because you don't have to wear heels for every occasion, opt for flats that feel just as special. 

The blend of retro florals, charming ginghams and kitsch polka dots in Rixo's dresses makes them our summer go-tos.

What to Wear to a Dinner Party 

The Best Occasionwear for Every Event - Dinner Party



Slick and stylish separates toe the line between refined glamour and casual cool when you're not sure how formal an event will be. Although there aren't any expectations to dance at a dinner party, why not use it as an opportunity to dress up?

If in doubt, sharp tailoring is always our fail-safe. 

Up the ante with an embellished version of this season's hero skirt: the mini. 

If you aren't already familiar with Piferi's luxury vegan shoes, the Fantasia sandals are the perfect introduction. 

When it comes to occasion jewellery, if it doesn't glitter, go for gold. 

What to Wear to a Wedding 

The Best Occasionwear for Every Event - summer wedding



Good sense says you should never upstage the bride (unless expressly permitted, head-to-toe white is off the table), but there's no reason to celebrate the union of your nearest and dearest in a muted outfit. After all, the photos will last forever. Our advice? Timeless silhouettes, mood-boosting colour, and comfortable shoes.

This full-skirted bouquet of pastel florals comes in linen to keep you cool at a summer wedding when the temperatures rise. 

The ideal mid-heel height for a comfortably stylish look. 

What to Wear to a Black-Tie Event

The Best Occasionwear for Every Event - Black Tie

The level of formality at a black-tie event means that men have to wear dinner jackets and bow ties and women are traditionally expected to opt for knee- to ankle-length dresses. But don't panic—it doesn't need to be a ballgown (unless it's a white-tie event), so play with colour, volume and texture. And enjoy!

There is no chance of being under-dressed with a statement balloon sleeve.

XXL sleeves deserve some XXL accessorising, and this piece is commanding big-necklace energy.

Calling all logo-maniacs! This iconic shoe has luxury written all over it.

There is something refreshing about this icy-blue satin.

The best thing about these earrings is their ability to grab anyone's attention.

What to Wear to a Birthday Party 

The Best Occasionwear for Every Event - Birthday party



If you can't go all out on a birthday, when can you? In fact, it's actively encouraged. So dust off your favourite party shoes for this most important of occasions, and when it comes to partywear, the more ostentatious, the better.

We called it: Micro hemlines are trending hard in 2022, and the bright-green print makes this gem stand out from the crowd.

A mini bag big enough for all of your night-out essentials.

Add a dose of fun with bright colours and crystals. 

The classic little black dress with a little extra cut-out detail.

Coco Chanel might have suggested taking one accessory off before leaving the house, but with jewellery this good, we're inclined to keep it on. 

The high-octane, glitter-drenched shoes you've seen all over social media are the pinnacle of occasion footwear.
