No,...to be honest neither one of them is actually named Klein. One of them, the blonde, is of German ancestry and Klein is the beginning of her name,..so I shortened it to Klein. The other one,...if you said her name really fast it might sound like Klein. lol
You are right,..I definitely look better with my clothes on,..and I don't think my models would appreciate me taking my clothes off. I don't know who your friend is,..but if they enjoy your work they had no aesthetic sense anyways.
