If you want to look a bit more voluptuous then a dress that's either a fitted sheath style, or an A-line can give the appearance of curves and help to accentuate your slender figure. Strapless styles however tend to make your shoulder and neck area appear even thinner.
To downplay your hips choose full-skirted dresses that make the waist appear thinner and also hide larger hips. Avoid any style that's form-fitting or that features a V-neckline, which causes the eyes to look downward making the hip area appear wider.
To minimize the bust strictly avoid dresses with V-necklines and look for those that feature a halter, sweetheart, or scoop-neckline that will help to accentuate the shoulders and minimize larger bustlines. Also steer clear of dresses covered in embellishments or busy styles that tend to make the chest appear bigger, as well as "fussier" fabrics such as velvets, taffeta, organza or organdy.
To hide a large backside avoid anything in clingy material or dresses in the sheath style, and choose from full-skirted gowns and dresses that will help to hide both your bottom and hips. Dresses with form-fitting bodices are also perfect for creating that enviable hourglass figure.
If you have a pear-shaped body ball gowns with fitted bodices are great for concealing a heavier bottom and accentuating a shapely waist and bust line.
To camouflage your arms choose your debs dress with sweetheart necklines, which help draw the eye to the bust and away from the arms. You'll obviously want to stay away from strapless dresses or those with thin spaghetti straps and instead opt for those with short to medium length sleeves or those with lacy or silky see-through sleeves. If you really must have a strapless gown, choose one that comes with an accompanying scarf or wrap, or buy one that matches or enhances your dress.
Flatten the tummy by choosing either an empire waist gown – definitely the way to go if you want to hide the stomach area and make it appear flatter – or one that features a corset-style bodice to make the waist seem smaller and the bust larger.
To appear taller stay away from elaborate ball gown style dresses or those that flare out all way to the floor. Instead, opt for an A-line, sheath, or silhouette style dress that helps to draw the eye downward and elongate the figure. Remember, when you're on the petite side, less is always more as a dress that's too busy will be overwhelming and make you appear even shorter.
