Experts tell us what not to wear

Trinny Woodall and Susannah Constantine, authors of "What Not To Wear" (Riverhead Books) and hosts of the BBC-TV show of the same name, say the most important things in developing personal flair and style is determining one's shape and what flatters it.

Here are some guidelines featured in their new book:

For a big bust, the best T-shirts have either a wide-open neckline or a V-neck while the worst choice is a high-neck, sleeveless T; the best jacket is very fitted with a deep V, with the hem cut to the hip and a small lapel, and the worst jacket is boxy and short-waisted.

For a small chest, the best dress choices are plunging necklines or high necks in a sheer fabric, and the worst have empire lines or spaghetti straps; the best tops are halters or sleeveless shirts with detailed front panels, and a corset is the worst.

For thick arms, the best dress has fluted sleeves -- and its even better with a small pattern, and the worst options are spaghetti straps or a sleeveless shift dress; the best bracelet is a delicate one, not a big bangle.

For a large rear end, look for side-fastening, loose-fitting trousers, and steer clear of high-waisted, tight pants, front pleats and tapered trousers; the best jacket is a tailored look that flares over the rear end, and the worst is a short jacket.

For a thick waist, the best tops are navel-deep V-necks and corsets, and the worst choices are baggy tops or boxy cardigans; the best coat is the long frock style with a nipped waist, and the worst are trenches and straight-cut overcoats.

For short legs, the best trousers are either palazzos or wide flares, while the worst choices are cropped or high-waisted; the best skirts are long (worn with high heels) or calf length (worn with boots), while a bias-cut skirt that ends mid calf cuts you off.

For a flabby tummy, try a ruched or wrap top, and avoid tight tanks; the best dresses have a low-slung waist or an empire line, and the worst has a "sprayed-on Lycra" look.

For saddlebags, the best T-shirts are boatnecks, while the worst is big, white and baggy; the best skirt is an A-line in any length, while bias-cut or pencil shapes are the worst.
