What do you wear to a casual holiday party?

Casual holiday parties are so much fun. Surrounded by friends, family, loved ones and close acquaintances, you want to make a statement while remaining comfortable and cosy. Wearing outfits like pant suits, jumpsuits or floaty casual dresses are the best selections for casual parties.

Wearing a pant suit like the Phase Eight Geri Glitter Pant Suit is a surefire way to feel comfortable without compromising on style. Flattering for all body types, this pant suit would be ideal for casual drinks or a sit-down dinner in a more formal setting. We recommend styling with a block coloured blouse in a bright hue like pink or red. 

Flattering jumpsuits are also a great garment to wear throughout the festive season. Easy to throw on, effortless to style, and completely comfortable whether you're dancing, ice skating, hitting the best Christmas markets or attending a casual holiday party with friends and family. We love the River Island Green Sequin Wrap Jumpsuit for a chic and festive take on the classic silhouette. Another garment that suits an array of different body types – what's not to love. 

Casual dresses make for the perfect outfit when attending family get-togethers and Christmas brunches with friends. The Marks & Spencer Animal Print Tie Front Midaxi Shirt Dress makes the perfect versatile dress for all manner of casual events. Pair with a tan Chelsea boot and a chunky cardigan or sweater for a casual and cosy off-duty look that you can wear time and again – festive season or not.

What do you wear to an office Christmas party?

Office Christmas parties can be either casual or formal – depending on the location, dress code and your place of work. If you're headed out for Christmas cocktails, a sparkling midi dress would make the perfect ensemble, but if you're headed out to a fancy restaurant or for a formal sit-down dinner, a chic and opulent gown might be more suited to the event.

If you're heading out for cocktails with a group of bubbly and upbeat colleagues, then the Never Fully Dressed Lurex Clash Midi Dress would make the most beautiful and bold statement. Go from day to night with this dress thanks to the multi-colored accents, and wear with your best winter boots in the day and heels at night. 

For a more formal get-together, the Chi Chi London Embroidered Off The Shoulder Flared Hem Midi Dress in navy makes a sleek and refined look that will be sure to keep in tune with the more formal and classy setting. 

If your workplace puts on a more black-tie-themed event for Christmas, then the Karen Millen Waterfall Maxi Dress might suit the occasion perfectly. A timeless silhouette always bodes well for more formal settings, which is why this waterfall style gown in a sumptuous velvet material makes the cut. Wear with pointed stilettos and a longline coat for the ultimate classic look, or wear a trench coat for a more Audrey Hepburn finish.
