She is definitely sabino, there is no question of that. Lots of leg white, which is all jaggedy at the top [and two of her socks/stockings come to arrowhead points], and symmetrical face white.
BUT... might there be a possibility of frame?
She has a LOT of ermine marks, indicating that something is trying to suppress the white on her legs. I haven't counted them but she has a whole bunch, and not just on her coronets. She has a couple of chestnut spots mid-cannon sort of region.
The other thing is, her face white is top-heavy and totally avoids the lower half of her face.
The horse I am most likely to breed her to is an Arabian [he puts divine fronts on all his babies, which is why he is top choice - because that's what I want to improve on with Magic] and thus far the wisdom is that the frame gene does not exist in the Arabian breed [nor do I see any traits in the stud I want to breed her to] but I would still like to know whether it would be worth testing Magic, or if I'm just seeing things.
The pictures don't really show the ermine marks that clearly but the face white is I think probably the most telling bit of white on her body. Experts... what say you?
