Looks are, of course highly subjective, but IMHO the whole ‘high class’ badge usually attaches itself to the surroundings as much as the lady or her level of service/enthusiasm.
I have punted some extremely expensive ladies over the years and rarely been less than totally satisfied with proceedings. Personally I would set the ‘high class’ bar in terms of base rate cost at £300 (not including extras). These punts always seemed to be in more luxurious locations than the cheaper SP’s tend to utilise, although there are always exceptions.
In terms of attractiveness, I have seen five such ladies:
Halle - Agency girl (who cost a fortune)
Nikki Jayne - AW
Biba - Agency girl
Marta Roberts - Indie
Nicole - Agency girl (long since retired)
Aside from all of them being stunners (again IMHO), the consistency with the price tag was their absolute devotion to ensuring I had a great time, the locations were spacious, well appointed and well stocked and the ladies themselves seemed to take great pride in their presentation (expensive lingerie, heels etc).
I’m sure there are plenty of ‘high end’ escorts out there who will happily take £300 and over to allow you to sit in their glacial, self-adoring company and provide little to know service, but as with all punts if things don’t feel right, then punters are well within their rights to leave before cash changes hands. Perhaps more applicable to costlier punts.
The two notable exceptions to my post are SPs who have provided all of the above for a fraction of the price. Gorgeous Vicky and ECB. Both of whom were very attractive and seem to consistently provide a full on GFE.
