lol pete
it's about models using stage names or alias' although i know plenty of photographers that do it too.
katie, you're so lucky having a cool middle name like estelle!!! mine is louise but a lot of commercial models use louise and my surname isn't cool enough i odn't think so i'd have to change that! you could definately pull off estelle chick!
i'm so glad everyone replied, as usual i got a bit of a bashing for bringing this topic up on various forums, yet i'm not surprised that lots of people do use it just as a matter of course, for many different reasons.
i think i'll stick with leighann lewis for England because it's a bit different, more grown up than using numbers in your name which is quite teenager-ish! and it has a ring to it i think, rolls off the tongue lol
but i still want everyone to know who i really am! otherwise what's the point in your 15 minutes of fame lol
