What to Wear to a Christmas Party and New Year’s Eve: The 16Arlington Edit

16Arlington is one of the most useful labels for the party season because it makes clothes for exactly these nights: sequin minis, fringe, feather hems and floor-length gowns, all cut with real tailoring. For Christmas parties and New Year’s Eve 2026 the strongest pieces come from the Autumn/Winter 2026 collection, in silver, copper and black diamond sequin, scarlet jersey and navy velvet. Here is what to wear for each kind of invitation, from the office party to a black-tie New Year’s Eve.

Key facts

• Sequin: the Sior mini in silver and black, the Amiata and Vesta midis, the Electra, Sesia and Alne gowns, and the Ossie top.
• Red: the Foyle gown and the Dora midi in scarlet viscose jersey, and the Jori top.
• Fringe and feathers: the Roia fringe mini, the Asha off-the-shoulder mini and the Melfa beaded-fringe mini.
• The sequin gowns and minis are lined in a stretch nylon and spandex for a close, comfortable fit.

The office party: a sequin halter top

Something with shine that still works with a jacket. The red Jori top, a slim jersey with a high neck trimmed in fringe, is the easiest answer with the Riva trousers. The silver Ossie halter top, worn with the ankle-length Tanaro satin skirt and a blazer over the top, moves from desks to drinks. The fuller list of trousers is in the trousers guide.

1. Jori Top in Red

Slim red jersey with a high statement neckline trimmed in delicate fringe.

2. Ossie Top in Silver

All-over silver sequin with a halter neck, long neck ties and an open back.

3. Tanaro Midi Skirt in Black

Ankle-length black satin with draping from long ties at the waist.

The Christmas party: a silver sequin mini dress

This is the night for a mini. The Sior is the house’s signature sequin mini with a square neck and a concealed back zip: silver for maximum shine, black with a feather hem for something more grown-up. The Roia, a one-shoulder mini fully covered in navy and black sequin fringe, is the piece that moves best on a dance floor.

4. Sior Mini Dress in Silver

Flat silver sequins over a sculpting stretch base, square neck, above the knee.

5. Sior Mini Dress in Black

The Sior in black sequin with a band of soft feathers at the hem.

6. Roia Mini Dress in Black and Navy

Navy and black sequin fringe with an internal corset, a one-shoulder neckline and a beaded fringe hem.

7. Asha Mini Dress in Black

A black off-the-shoulder mini with a band of ostrich feathers along the sloped neckline.

8. Melfa Mini Dress in Black

A straight black mini with ballooned long sleeves, a wrap effect and seams trimmed with handmade beaded fringe.

The dinner

A midi in sequin, velvet and jersey reads as dressed without competing with the table. The Amiata is black sequin with ruched cups and a keyhole tied with silver-tipped ties. The copper Vesta has a V neck and a front split. For something softer, the strapless navy velvet Minelli and the scarlet Dora jersey with its cape detail both work.

9. Amiata Midi Dress in Black

Black sequin with ruched cups, a keyhole at the chest and a nineties straight skirt below the knee.

10. Vesta Midi Dress in Copper

Copper sequin ruched at the waist with a V neck and a front split.

11. Dora Midi Dress in Red

Heavy scarlet viscose jersey draped from a high neck through a cape into an ankle-grazing skirt.

12. Minelli Midi Dress in Navy

Strapless navy velvet with an internal corset and a feather hem.

New Year’s Eve and black tie: the black sequin gown

Floor length, and as much light as you can carry. The Alne in copper sequin has a high neck, long sleeves and a puddle train. The Foyle is a slim scarlet jersey column with scarf layering at the neck. The Electra is the house’s signature square-neck sequin gown, here in black diamond sequin. The Sesia, in black flat sequin with flared sleeves, is the most formal. For a strapless option the black devore Frasia completes the set, and every other long dress is in the gowns guide.

13. Alne Gown in Copper

Copper sequin with a high neck, long sleeves and a puddle train.

14. Foyle Gown in Red

Slim scarlet jersey with scarf layering at the neck, pooling at the floor.

15. Electra Gown in Black Diamond Sequin

Black diamond sequin with thin straps and a square neck, darted at the bust and closed with a concealed branded zip.

16. Sesia Gown in Black

Black flat sequin with a wide square neck, slightly flared sleeves and a skirt split.

17. Frasia Gown in Black

Strapless black devore with an internal corset, pooling at the floor.

Styling for the season

With this much embellishment, keep accessories small: a slim clutch, a single earring and a sandal in black, silver and gold to match the sequin. For cold nights, put the Rosalind coat over any of the gowns; its fringed scarf picks up the shine. If you are dressing for a wedding over the holidays, the wedding guest guide covers what to avoid.

Sizing

The sequin pieces are lined in a stretch nylon and spandex, and the Sior and Sesia have stretch in the sequin itself, so take your usual UK size. The Foyle is slim and the corseted Minelli and Frasia suit a precise size. The brand’s model is 178cm and wears a UK 8. Full conversions are in the size guide.
