Want a more “impressive” look in low cut sundresses and evening gowns? Do your own photoshop effect, just like you see in the catalogs. Take the same highlighter product you would use on your cheekbones and draw it in a semi-circle across the top curve of each breast. Blend into skin til you just see a gentle glow. Then use a contour product like a medium brown eyeshadow or bronzer (with no sparkle, shine or reddish tone to it) to deepen the natural cleavage shadows that the breasts make if you wear a push-up bra. Leave a little space between the shadow you create on each side and make sure it curves like you do. BLEND carefully with a sponge. The shadow should blend out to nothing at the very top and look natural as you move in the light.
