I typed these up for a Gamefaqs character combo FAQ so I'm just going to copy and paste. A lot of these combos were found by members here like Ninj, Helter Skelter, Drayn0, and myself. These are subject to change since more and more combos are being found by the community. So here are what I think are her BnB's:
Basic No Meter BnBs:
2, 1, 2, Dagger Toss, Dagger Cancel, 2, 3, Dagger Toss, Dagger Cancel, 1, 1, 2 (29%, 10 Hits) <-- Credit to Ninj <-- You can add a Red Dash at the end if you want, as it leads to her 50/50 mix-up
B+2, Down Slash, B+2, Down Slash, dash, 2, 3, Red Dash, Up Slash, dash, 2, 3, Red Dash, Red Slide (45%, 10 Hits)
B+2, Down Slash, dash, F+2, 1, 2, 1+2, Red Dash, Up Slash, dash, 2, 3, Red Dash, Red Slide (38%, 11 Hits) <-- First dash is not necessary but you'd need more timing w/o it
F+2, 1, 2, 1+2, Red Dash, Up Slash, dash, F+4, Red Dash, Down Slash, dash, 2, 3, Red Dash, Red Slide (39%, 11 Hits) <-- Credit to Ninj <-- Hard to do, Easier version is below:

U+3, U+3, Air Dagger (Far), dash, 2, 3, Dagger Toss, Dagger Cancel, 2, 3, Red Dash, Red Slide (42%, 9 Hits) <-- Credit to Helter Skelter <-- You can also use this as a punisher for blocked teleports that puts the opponent in a ball roll animation
(Wall Combo) F+2, 1, 2, 1+2, Down Slash, B+1, 1, F+4, Down Slash, B+1, 1, F+4, Down Slash, 1, 1, 2 (45%, 17 Hits) <-- Move backwards a little before the first B+1
(Wall Combo) F3, 1, 2, Down Slash, B2, Down Slash, B1, 1, F4, Down Slash, B1, 1, F4, Down Slash, 1, 1, 2 (47%, 17 Hits) <-- Hit confirmable (not exactly sure on damage without the jip but I'm estimating 47%)
