Wear long dark pants: Wearing long dark pants will detract from any flaws on the lower half of your body. Wearing a light colored or white top will also add to the illusion and distract from your lower half. You will want pants that flow and flair for the best look.
Bootcut Jeans: Bootcut jeans are the most flattering for the flawed figure. Finding a pair that flairs a bit will provide a long and lean appearance. Dark jeans are best if you are trying to camouflage your weight.
Wear the right size: Wearing clothes that are big will not hide your weight. In fact, most times it will make you look bigger. Get rid of the bulk and wear the right size. Throw on a cardigan or jacket to cover your trouble areas.
Monochromatic look: Wearing all one color will give you a slimmer appearance. If you want a splash of color throw on a scarf or funky pair of shoes.
Pencil Skirts: Believe it or not a pencil skirt looks great on any figure. Just get the right size and make sure it is not skin tight.
Heels and Jeans: Dress up those jeans with heels and you will add length to your body. Adding length distracts from width.
V-Necks: V-necks look great on everyone! Wear on a black V-Neck with black boot cut jeans, red heels, the right belt, and perhaps a long lightweight cardigan and you will look amazing!
Dark and Light Colors: Layer your dark colors under your light colors. For instance, wear a dark navy shirt with a white form fitting cardigan.
Match Shoes to Skin: Find a pair of shoes that matches as closely to your skin tone as possible. This will give you a leggy look. Try to wear heels an inch or higher for the best effect.
