Sometimes it's the outfit. For instance the second ever escort I saw was Jade at the Chicken, chose her solely based on her outfit, a very sheer black teddy that showed off her breast very well. Well that and the nice ornery smile on her face that didn't once fade during the entire lineup.
Sometimes, such as with Jessica Marie at the Love Ranch, Ruby at the Sagebrush, and Anna Suvari at the Bunny Ranch, months of PM's back and forth between us that convinced me to see her. In Ruby's case I lucked out because day I visited she wasn't scheduled to be there, and I had made tentative plans to see her later that fall. I was about to leave the Sagebrush when who walks in but Ruby. Both the Sage and I lucked out that day.
Other times the lady's personality outshines all others in the place, three such ladies were Jimi Lynn, Latina and Vanessa at the Wild Horse. In the case of Latina, I was hooked the moment she walked into the bar in this really elegant and sexy dress that accented her large breasts, and at the time a very tiny waist. She seemed like a 1940's movie starlet walking down the red carpet. She was a little shy at the time, but her presence outshone all the other ladies.
Other times it was conversation in the bar. For instance one of the best parties I had occurred with a lady named Faith at the Kit Kat. We talked for over an hour before I finally asked her on a tour, and by the time we arrived at her room I think both of us were ready for some fun, because that was one of the few times the lady took my initial low offer.
In other cases it was reviews alone, such Coco at Inez's. When I entered Inez's I was greeted by this very peppy and sexy woman, in a very revealing outfit. She asked if I was here to see anyone in particular and offered a tour or to get some more ladies before she even mentioned her name. When I asked her name and she said Coco that was all I needed to immediately agreed to a tour and party. I would have likely chosen her anyway but her reviews clinched the deal.
Finally in some cases you can never tell what makes a guy choose a lady. Case in point is a lady I regret not being fast enough to ask for a tour. This occurred during the visit when I partied with Faith at the Kit Kat. Another lady named Isabel had just walked into the bar looking like she had just awoken. She had came in coffee cup in her hand, wearing a bathrobe and her hair was still wet from the shower. I was about to ask for a tour, but was beat by one of the other customers who had just walked a few minutes earlier.
