So look for subtle details that will make your LBD eyecatching: the black patent trim on this winter's v-neck, sleeveless wool tunic from Victoria. Victoria Beckham is a textbook example of a successful LBD update - and less screechy than Kate Moss' all-over wipe-clean number. An asymmetric neckline, peek-a-boo detail, contrasting sleeves, generous bow and contrasting textures are others - and can also be used strategically to contour your body and distract the eye.
Finding the perfect LBD in 2014 is an exercise in keeping your nerve. The cut and quality of LBDs vary wildly, even when you're paying top dollar. If you're on a tight budget, rest assured there are good high-street versions out there, but you'll need patience and stamina not to cave in after the 19th inferior one.
Puckered seams, the wrong kind of shine, snags, awkward lengths, cheap-looking lace, tacky embellishment and dresses that are simple without being in any way special (it's all in the cut) are to be avoided. The simpler the LBD, the more glaring the tiniest flaw. But get it right and, as Coco promised, you're on to a winner that's guaranteed to stand the test of time.
THE BODY POLITIC: FIND THE LBD FOR YOUR SHAPE
• The best necklines for big boobs are V-necks, boat necks, keyholes or square frames that lap the shoulders, creating a statuesque frame that makes the figure look elegant and in proportion.
• A raised waistline makes legs look longer.
• A-line skirts skim pear shapes - the longer the better. Pleated chiffon skirts can also be extremely flattering.
• Full silk skirts, either ballerina or floorlength, can look fabulously sophisticated with a simple top or slim, short-sleeved cashmere sweater (a la Carolina Herrera), but check the rear view before buying. A stiff fabric that holds its shape well without puffing out at strange angles, and front pleats, can help create a smooth silhouette.
• Asymmetric necklines can be extremely alluring, especially when they're semi-sheer. They're particularly good on small busts.
• Gladiator and strappy heels can stop a plain black dress from looking blah, but only if the legs attached are sensational. If your LBD is so simple that it requires extra shoe drama, but you don't have the calves for ribbon-ties, opt for colourful, lustrous fabrics, jewels, embroideries, laser cut-outs, buckles or even pom-poms. This is not the time to be coy with your footwear.
• Wearing two pieces is a good way to achieve the figure definition you want if you can't find a dress that fits. So is a dress that wraps or ties.
• Prints can be amazingly effective at distracting the eye and disguising fuller figures.
• High necklines and collars can look beautiful - on the swan-necked. Anyone else should avoid them.
THE LITTLE BLACK DRESS BACK-UP TEAM
Actually, this is more of a props list for any party outfit, be it LBD or Big Pink Ballgown. Keep the following neatly stored in one accessible place and regularly check they're up to date and in pristine order.
• A sparkling evening clutch.
• Jewelled evening shoes.
• Velvet or satin open-toed shoes.
• A multi-way bra. It doesn't have to be black: dark oyster could be more useful and it won't show under semi-sheer black tops.
• Shapewear - from a light touch to corset-strength, it doesn't hurt to have all the bases covered.
• A metallic belt, a patent belt and a shiny box-leather belt, depending on your mood. Build a repertoire of these gradually.
• A cropped jacket or wrap-style jacket with bracelet-length sleeves is the most versatile option. It will work over any length of dress and most shapes. Textures are a good idea because if your jacket is also black, it won't matter if it's not the same shade as your dress. It doesn't have to mean conventional "evening fabrics". This could be the moment for a black
leather jacket.
• A good quality fake-fur tippet. However skimpy your outfit, this will keep hypothermia at bay.
• A flesh-coloured slip, ideally silk or satin - synthetic can whip up a storm of static.
• Diamonds, real or fake.
• Pearls, ditto.
• Finally, keep your feet pedicured. You never know when an outfit will call for exposed toes.
