Best cocktail dresses: The 12 dresses that will ensure you dazzle at any party this season

While the invites never really stop, as we head towards the Holiday season, the best cocktail dresses suddenly become a key part of our wardrobe. Whether you've got work parties to attend or a winter wedding in the diary, finding the perfect cocktail dress to toast any celebration is a surprisingly tall order. 

The best cocktail dresses tread the fine line between occasionwear without going OTT. Not quite as formal as black tie clothing but not as casual as your favorite jeans and cute top ensemble, a cocktail dress helps to instantly up your style game, making sipping that champagne even more enjoyable. But what makes the best cocktail dresses stand apart from your regular best dresses? A cocktail dress is made to be worn for evening events, which means it automatically demands a sleek and sultry twist. 

While your day dress might feel light and bright, for evening cocktail wear you will want to consider more jewel tones, as well as classic darker hues of navy and black. Fabric is important to consider too, more tactile fabrics such as velvet and light-catching silks replace daytime linen and cotton for a dramatic finish. You might also want to consider embellishment details. Lace trims, pretty beadwork, feathers, or sequins might feel a lot for a day outfit, but come cocktail hour, you can easily weavee these finishes into your ensemble.

When it comes to silhouettes, there are no hard and fast rules. As a general guide, we recommend opting for a midi, knee-length or thigh scraping style, as traditionally maxi or gown length dresses are not worn for cocktail events, however as hem lengths are often dictated by the latest trends, there is some wiggle room, if you'd prefer to go for a longer skirt length.

The main thing that sets a cocktail dress apart is the leaning towards more luxe fabrications and the use of embellishment detail. This means that you can concentrate on picking a silhouette that you feel most confident in. Here are 12 cocktail dresses we're loving for the season ahead.

This lovely ruffled dress is ideal for a cocktail party. The tiered ruffle gently skims your middle, making this one of the most stylish dresses to hide a tummy. The dark navy hue makes a welcome change from classic black and is much more flattering on all skin tones.

Best places to buy the best cocktail dresses

When it comes to where to buy the best cocktail dresses, as a general rule of thumb, we would start with retailers who you know do standout partywear. Cocktail dresses aren't hugely different from other special occasionwear looks, so shopping with retailers and brands you have been successful with in the past will hopefully contribute to an easier shopping experience. 

Occasionwear, such as cocktail dresses can be a little more fitted than everyday pieces, so you might want to try a few different sizes, especially if you've not purchased party items from a label before. You also will want to make sure you're wearing a bra with good uplift and consider some shapewear for the smoothest of finishes.

Of course, as we head towards the Holiday season more and more retailers will be offering special occasion lines and this is the best time to stock up on cocktail dresses. For pieces that will work year through, invest in metallic hues, or classic black and navy designs as these will become great fallback options that can constantly be reinvented.
