I do agree with Naomi that professionally beautiful people work very hard at it indeed, and that clever use of contouring can turn miss piggy into the Mona Lisa, and starving yourself and working out 4 hours per day can be considered work, however essentially genes factor in it massively also and there is a limit the non naturally pretty can reach, once you're very put together, thin, tanned, dressed well, made up well, there is nowhere else for your big nose to hide.
