A right midi skirt will do you a good turn, it is everything you can ask for - comfortable, flattering, and very fashionable. Midi skirts made it to the list of maternity clothing staples.
Skirts that hit at your knees have slimming, elongating effect. Get one in dark colors and your extra pounds visually disappear, as if they have never been on your hips and thighs. Pencil skirts are the best double-agents. Change your formal button-down shirt to a bright sexy cami, top off the outfit with bright accessories, and trade flats for kitten-heels.
