Shapewear
Invest in shapewear. It is quite an effective measure helping you look absolutely different in a matter of seconds. There are a lot of brands of shapewear. Pick the one you trust most and enjoy the result: smoother and thinner shape, no bulges and trimmer silhouette. Spanx does work wonders!

Opt for Black
If the top and the bottom of your ensemble are of contrasting colors, you will not look as slim as you would if they were a match. Let your clothes be of the same color. Black is always in fashion and you will never go wrong with it. However, if you prefer something different, go ahead and pick your favorite. Opt for darker shades though. Use brighter accessories such as scarves, or jewelry to create your own style.
