Who fits the physical description will tell you that she is perfect for the date..  

When you have dinner dates or extended dates on the first meeting it's always a risk. I'm sure you are no dum dum and were highly aware of this..  

I wouldn't stress to much on that part, just cross your fingers and hope that your conversations can go with the flow..

That being said, I can be 5'7" in heels.

You would never be disappointed with Trinity from 100proof. All you described.

Choose wisely grasshopper .......

Because the selection of beautiful ladies in Vegas is endless ! They have never disappointed me !

an extended date when meeting for the first time. It would be like going on a blind date that your friend set up for you. There are a lot of beautiful women in Vegas, but everyone has their own definition or standard of what they consider "educated" and "intellegient". Maybe meet for a couple of hours and if you hit it off then ask to extend the date.

hey are so positive you can read a book by the light of their smile,  

And if you can "suffer" a little bit with a girl with big boobs, perfect dinner dates (smart, positive) in Vegas are:

April Luv (good at picking restaurants)
Heather D'Angelo
Cindy Spice

Recently I also met and talked with a girl at a party that fits your physical and social description, but we haven't dated

Arden Moon
