She looks very much like my guy who is supposed to be a YorkiPoo. He's about the same size/ Some people have commented that he looks like he's a YorkiSilky also. His ears never stand up fully when trimmed, just go up half-way.
The second picture shows him at 3 months old just to give you an idea of how they change.
It's great you found each other!
In any case she's adorable and has great fashion sense!
