whatever she did, its working. i think she looks amazing in both but the second shot is far more flattering. ladies, if you take pictures for your sweetie, that second pose does justice/shows mercy to almost anyone. trust me, i stole the idea from a centerfold pic i saw.
1.)even a woman who is very gamine (skinny)will look great because she will likely have amazing legs.
2.)even a woman who is a bit plush will look great because the tensing of the muscles does soemthing for hips and thighs.
3.) a woman with big chest who would envy it to have a beyonce backside will look great because the hiding/showing of the chest from that angle looks great. Implied but not 100 percent exposed breasts, sensual and very classy.
