What a cutie! I love those little ear tufts in the first picture. It looks like she has an M marking above her nose (a characteristic of tabbies) so I'd call her a bicolor ginger tabby. That's not a breed, though, just a coat pattern.
 There are various types of tabbies if you want to narrow it down more: striped, flecked (or speckled), bulls eye, spotted (or dotted), etc. I can't tell from your photos what kind of markings are on the orange areas of her body.
