I’m Already Facing A Full Diary Of Events – And I’m Relying On This Grown-Up High Street Partywear

Don't fret over what to wear this festive season – this high street label has you covered.

Whether you're a deck-the-halls-before-December type or a last-minute mulled wine maker, you can't escape the onslaught of parties which run throughout the last two months of the year. Short of climbing into bed and refusing to move until 2025, there are things which can make endless events much easier – a fail-safe wardrobe, for one. If you're already feeling somewhat bemused by the idea of sequin dresses and tinsel-trimmed tops, fear not, as there's one high street brand whose partywear offering is a chic, grown-up take on festive.

The trick to navigating party outfits, particularly during such a busy time, is to identify key pieces on which you know you can rely. Whether that's separates, a dress or an all-in-one, finding even just one item that makes you feel fantastic is the answer – you can always change your accessories to style it differently for multiple events. Whistles' new partywear collection is full of such items, from wear-everywhere LBDs to elegant velvet jumpsuits, completed by some glitzy add-ons to elevate any outfit.

For the low-key party goer, there are silk shirts which would make a wonderful addition to jeans and heeled boots, while mini dresses in gold lace and black velvet are suited to the maximalist approach to after-dark. Tuxedo jumpsuits could be worn over white shirts with flats for day, before being transformed with heels and drop earrings by night, meaning you only need to pack a change of shoes. Similarly, satin maxi dresses would work layered under an oversized blazer, which can then be stored in the cloakroom as you find the dance floor.

Whistles really is one of those brands which understands how women want to dress – and what we need to consider in practical terms, too. So, whether you're short on time or need something to take you to the party straight from work, this collection does do it all.

The ultimate LBD, this velvet dress will look fab with sheer tights and embellished heels for a timeless take on party dressing.

If you're a jeans-and-a-top kind of dresser, this cami is the answer to all of your problems. Throw this on and add ankle boots or heels for a fail-safe occasion outfit.

Gloriously chic, this satin dress would work under an oversized blazer to dress it down – or wear on its own with platforms and really great jewellery to be the best dressed.

Even if you've only got 10 minutes to get ready, throw this on with a pair of knee high boots and oversized stud earrings and you're good to go.

This is a truly special piece which will live in your wardrobe forever. An all-in-one outfit, you only need to add your favourite accessories and you're ready for any event.

If you are a die-hard sequin fan, this is the party piece for you. Contrast the sparkle with a cropped black jacket and pointed pumps.

The perfect party bag, this was so popular last year that it sold out. Now, it's back, and ready to be your best friend on a night out.

For a more subtle take on sequins, this is a stylish twist on the classic shift dress. Ideal for winter weddings, layer under a velvet coat to create texture.

Fabulous party shoes which are comfortable, too? It may seem too good to be true but, thanks to these mules, it isn't. Wear with everything from party frocks to cropped jeans and silk shirts.

Long sleeved party dresses can be hard to find – especially when they're as lovely as this. Team with ballet pumps and tights for an easy outfit.

Just add this to jeans and a pair of heels and you're ready for any party.

You could wear this skirt with almost any top and you'd still dazzle on the dance floor. Try with pointed court shoes and a navy cami top for the perfect drinks outfit.

A silk shirt is one of the most versatile pieces you could hope to have in your wardrobe. Wear with tailored trousers for work or tuck into high-waisted jeans for a low-maintenance party ensemble.

A pair of party pants will stand you in good stead to put together endless event outfits. This pair has a great cropped fit – wear with your favourite party shoes to show them off.
