Stiletto sounds like it would be a nude/topless model agency, not lifestyle/event modeling. Novikko is going to be difficult for people to remember and know how to spell it - and you want people to be able to find your website easily. What about Nova - easy to pronounce, spell and remember
Stiletto is somewhat sexist (I mean most people will associate that term with very high heels worn by outlandishly dressed dominatrix types) I guess if you want to be neutral - Novikko!
