Where: Roundhouse, Camden
Joanne Black style: Grey wool Lanvin dress, YSL heels, Alexander Mcqueen clutch and Stephen Webster choker

It is not always easy to survey the style scene when you’re at a sit-down dinner. So, I was quite excited when a smoke alarm went off during the starters, forcing the 1,000-or-so guests to congregate outside.

With Stella McCartney, Matthew Williamson, Kate Moss and Liz Hurley among the diners, there was definitely a lot to see. Liz Hurley looked stunning in a see-through blue/grey sari-style dress and I wasn’t surprised to see her rush inside once the event restarted – she must have been freezing! Host Natalia Vodianova also looked striking in a LV fall 2009 puff ball dress and LV burgundy shoes.

Brief glitch aside, Vodianova’s ball was a huge success, raising over $1 million for The Naked Heart Foundation, which builds playgrounds across Russia. Ruby Wax put in a lively performance as compere for the evening and Leona Lewis looked beautiful as she sang in a rust and gold asymmetrical William Tempest dress with Alexis Bittar bangles.

Issa London Autumn/Winter 2011

Where: Somerset House
Joanne Black style: Jitrois leather leggings, Golden Goose check shirt, black Miu Miu boots, a Brunello Cucinelli cardigan and Prada jacket

Brazilian-born Issa knows how to put on a show. Her star-studded audience – which included Princess Beatrice and boyfriend Dave Clark on the front row – were treated to a collection of leather trousers, beautiful red capes, jersey and stretch wool outfits and wannabe red carpet dresses.

The clothes, however, told a very British story. Prints narrated a day in the capital – among the building and bad habits – and the grey and overcast weather influenced the autumn/winter colour palette. People watching also played a huge part in the designs. Issa describes being inspired by taking a black cab around London – and by watching faces at The Wolseley, Scott’s, China Tang, Annabel’s and Dover Street Market.

As well as fabulous pieces – model Alice Dellal dazzled in a halterneck dress and I already have my eye on the floor-length asymmetric black dress for my upcoming Oscar party – there was some great statement hair on show. Barry Martin and stylist Malcolm Edwards should be applauded for their attention to detail.

Osman

Where: Somerset House
Joanne Black style: Jitrois leather leggings, Sergio Rossi over-the-knee boots, Zadig & Voltaire polo neck, Sharon Wauchob coat, Chanel bag, and Damiani earrings

There are only a few things that will get me out of bed the day after a post-Bafta party – and fresh designer Osman’s autumn/winter collection is one of them.

What this man doesn’t know about jersey just isn’t worth knowing. When four models opened the show in beautiful purple jersey dresses – draped in a Grecian style – I knew we would be in for a treat. Osman, who believes Cate Blanchett would be his ideal customer, loves strong, stylish female figures with a sense of adventure. This certainly came across in his show. Hot pinks added a splash of confident colour to the runway – Osman even joined in with bright pink socks and a shirt – a striking dresses, tops and trousers showed just how versatile jersey fabric can be.

Best look of the show? It has to be the grey check and leather jacket, worn over an icy grey long jersey skirt. It was elegant, chic and worthy of space in any wardrobe.

Joanne Black style: Nicole Miller LBD, YSL heels, Damiani earrings, and a Chanel bag

What could be better than spending the day surrounded by beautiful clothes? Spending the day and night watching the latest fashions – and the fashionable – come to life.

The Bafta after show party was a style-spotting extravaganza. Here are the highlights…

Best dressed: Best Actress winner Carey Mulligan takes away my first award for her stunning black and white figure-hugging floral dress. She told me it was by famous French fashion house Vionnet, which was started by Madeleine Vionnet – the queen of the bias cut.
Best supporting style: Carey celebrated her win with sisters Mary-Kate and Ashley Olsen. Mary-Kate looked fab in one of her favourite Astrakhan coats and Ashley showed us how to play it cool in a cream trench coat.
Best leading man: Ok, I’m torn on this one. Nominations include the dashing Colin Firth in a Tom Ford tux, and Matt Dillon and James Nesbitt – also sporting the tux look. I think, however, Josh Hartnett clinches it with his effortless style – grey beanie, a black leather jacket, red check shirt pulled and blue jeans.
Best star turn: Anyone would have thought Precious star – Gabourey Sidibe – had won a Bafta the way she was smiling. Wearing a taupe and gold floor-length dress with flat shoes, she oozed star quality.

Inspired by Dimitri Chiparus' sculptures

Signature Knitwear by Mark Fast

Where: Flowers Cellars, Covent Garden
Joanne Black Style: Prada Jacket, Zadig & Voltaire Jeans and polo neck, Ash boots and an Alexander Wang bag

The man who put plus size models on the catwalk is back. And with women such as Crystal Renn taking to the runway, Mark Fast certainly knows how to show big means beautiful.

If you’re going to wear knitwear, it has to be Mark Fast knitwear. Influenced by the bronze sculptures of Dimitri Chiparus, the colours of coral and sea creatures and winter warmth, Fast’s Autumn/winter 2010 collection makes great use of his signature elastomeric yarns, which are designed to cling to anything that moves. But as well as his short, tight and stretchy style, Fast fashion now includes waterfall scarf trails, capes, full skirts and sari-style stoles.

It seems Sarah Brown, the Prime Minister’s wife, approves of Fast’s sexy knitwear. Sat on the front row at the show, she looked lovely in a skirt by eco-chic label People Tree and v-neck sweater by Marks & Spencer, which she dressed up with a large stone pendant from jewellery label La Diosa.

Fast designs clothes for the ‘woman who knows exactly what she wants and takes risks’. That’s why if you’re looking to stand out this autumn you’ll need to slip into one of his colourful body con knit dresses.
