Andrea's It List: 6 timeless party dresses for every event this season

It’s the puff sleeves on this stylish Rotate Birger Christen dress that really set it apart. The unique back fastening also adds a touch of interest, yet it's classic enough that it won't date. Also available in silver.

Ok, it's not actually a dress but I love a jumpsuit for special occasions partly because you know that in a room of little black dresses, you're sure to stand out from the crowd. There are so many show-stopping ones to choose from at Nadine Marabi but I love the silhouette of the crystal-embellished Luna in black velvet with its tight-fitting trousers and loose 70's style top.

I recently spotted this Self Portrait dress on a guest at The Fashion Awards and loved it so much I had to ask her who it was by. The skin-tight stretch woven fabric creates a beautiful - slightly risque - silhouette, which is perfectly balanced by the demure high neck and padded shoulders.

This metallic dress from Mint Velvet with a layered hem and three-quarter-length sleeves is reminiscent of the iconic Vampire Wife style. It's elegant enough for a cocktail event but can be dressed down with a blazer and boots. Super flattering on and very reasonably priced, too.

If you're looking for timeless elegance, Victoria Beckham is a reliable bet. I'm currently eyeing up both these jersey dresses, and I can't make my mind up which is my favourite so I'm including both. Style the mini dress with opaque tights and ankle boots for date night or dinners with friends and the midi one with classic courts or strapless heels for formal events.

I'm a big fan of the simple slip dress. Stylish, elegant and yet super comfortable if you're planning on a night where you'll be spending most of the night on the dancefloor or sitting down after dinner, it's an all-round winner. This Reiss one in slinky satin comes in silver or indigo and features a cute side slit and unique rider back detail.
