Last month it was a lavish lace, Tom Ford ensemble and this week it's a skimpy piece from the Azzaro Autumn 2011 collection, worn for an appearance on The Late Show With David Letterman. The clever combination of long sleeves and a bum-skimming hemline ensures that you can still be seductive whilst staying warm in the colder months. Emma pulls this style off flawlessy with her enviably toned pins. The LBD that Emma was flaunting so beautifully is typical of the recent Azzaro collection which is signified by it's stylishly simplistic designs embellished by statement detailing such as sizeable velvet bows and Peter Pan collars. Emma's dress is bedecked with a crisscross metallic lace across the plunging, peekaboo neckline, reminiscent of corsetry and in keeping with the fetish fashion trend. The colour palette of this collection is almost exclusively monochrome adhering to the monotone nature of Autumn/Winter 2011 styling within the fashion world. Natalie Portman and fashion blog regular, Emma Watson have also been spotted dressed in elegant Azzaro designs. Ms. Stone teamed her micro-mini with skyscraper, Brian Atwood Venus Pumps in maroon to add a touch of Autumnal colour blocking and a timeless Irene Neuwirth ring.  With glitzy embellishment already incorporated within the design, you can stop worrying about the perfect accessory and keep adornments to a sophisticated minimum. Take a look at our editor's pick of the best long-sleeved minis, which will add a sprinkle of sass when you're wrapping up for the cooler seasons.
