To be honest, the beginning of the end was like three or four seasons ago, when she stopped walking Marc Jacobs, Anna Sui etc in NYC, Dolce and Gabbana, Versace and Gucci in Milan, and Chanel, YSL and Miu Miu in Paris.
It happens with everyone. Even models like Jac and Frida and Sigrid who usually walk 50+ shows aren't doing nearly as many anymore. Careers slow down once a model hits her late teens/early twenties. Just how the cookie crumbles. Or maybe this is just an off-season.
Vlada's pretty much at the *** end of her runway career, and I'm just glad we're seeing her at all doing the odd show, seeing nobody who started in 2004/2005 is even anywhere around anymore.
