Rosettes are in style right now. Why not don a summer dress that features a huge one at the center of the neckline?

Such a huge rosette will draw attention to your collar bone and its extra large size will make you look thinner by contrast. It will be surprisingly flattering. Don't think wearing black is the only way to create a slimming visual effect.

For those of us with curves, it is important to cinch the waist. Otherwise we would look bigger than we actually are. 

Last but not least, if your dress reveals your calves, don't put on shoes with ankle straps. Those would optically shorten your legs. If you like straps or bows on your shoes, they should be positioned below your ankles, like the bows on my shoes, to do your calves justice.

Happy summer!
