I saw Katy a few weeks back but didn't get round to a review, but I can back up all the positives mentioned here. She's an attractive, warm, friendly and downright sexy lady.
As for the 'is she a large or small 12' question....thats a difficult one to answer as she is a tall lady. She's probably dead on a 12, but because of her height she may look deceptively curvier. Regardess, she is top notch and well worth a visit in my opinion.
