You are welcome. I hope this helps. I love the marbled pattern in cats. I am not sure about the breed, probably domestic short hair but others will be along to help you too.
I agree with the above. Domestic short hair, DSH. The overhelming majority of all cats are domestics, so she is in a good company!
The pattern is classical tabby - called also for marbled, blotched or bulls eyed. The color is brown and white, you could probably say a tabby tuxedo.
Tuxedo is often said about the black and white cats, but it nicely describes the amount and layout of white.
A pretty girl! Looks a litte as young Birgitte Bardot! (Oh, memories arise! Whom more remembers Birgitte Bardot!!?? A good sign Im beginning to be an oldie)
