One thing about heels that I'll recommend (also as a photographer - and I agree with the above) - learn to walk in heels. The thing that makes so many women look uncomfortable is that when they're in heels they shorten their strides and take these little mincing-kitten steps.
Learn to really walk in them ... take your normal length stride. Really stretch it out there. You look better when walking and you get a little more hip action going.
And you don't look like you're hobbling around on mom's dress up heels!
