That wouldn't be to garishly inappropriate if subtly done - even if it was not 100% correct.
There's no way for tiger skin to be subtle (unless it's on the beast himself, in a mottled jungle).
All the fur coverings I've seen on breastplates are post 1600.
Leather covering for the top plate of the breastplate (assuming there is a top plate, and assuming it is covered with leather) is of a rather standard form, with no deviations I know of.
Since somebody is likely to do it one way or another, one could possibly find a textile pattern that, while NOT I REPEAT NOT being tiger in pattern, evokes something similar. Sone of the banded cloud motifs, for example. Then those textiles, in proper colors, of course, could be used, properly, for certain of the various garments worn with armour. This is about as close as I would go.
This is not license to go and buy tiger stiped fabric for your hakama, but it is a license to be laughed at if you do.
Disclaimer: I have a chink of tiger fur (fake) that I plop over my camp stool. Though it was a looong time ago, I recall reading that at some time, it was considered pretty chic to have gone to the continent to hunt tiger, and that the faux-chic bought skins from China to look fashionable. But I don't recall any mention of use other than for a seat cover similar to what I do, or covering a scabbard, or haning a piece of the tail therefrom. But hey, that was at least 20 years ago, and a lot of stuff from then has been superceded by better scholarship.
